e5dc768 bootstrap: Port back to old shells (#13199)

Brad King e5dc76894a bootstrap: Port back to old shells (#13199)
Since commit f39e82c9 (bootstrap: Re-implement command line option
processing, 2011-12-16) bootstrap uses POSIX shell expressions of the
form "${x#y}" to remove prefix pattern 'y' from the vaule of 'x'.
Although this is allowed by POSIX old shells on some platforms do not
support it.  Revert to using 'sed' to work with old shells.

Brad King e48796b26b KWSys: Fix SystemTools environment memory handling (#13156)
The SystemTools::PutEnv function tries to provide the "putenv" API
without leaking memory.  However, the kwsysDeletingCharVector singleton
frees memory that may still be referenced by the environment table,
having been placed there by putenv.  If any static destruction or
processing by an external tool happens after the singleton is destroyed
and accesses the environment it will read invalid memory.

Replace use of putenv with setenv/unsetenv when available.  The latter
manage internal copies of the values passed instead of referencing the
original memory.  When setenv/unsetenv are not available use putenv with
a singleton that removes its values from the environment before freeing
their memory.  This requires an "unputenv" implementation.  On at least
some platforms it must be written in terms of "putenv" because other
APIs are not available and direct modification of the "environ" global
is not safe (e.g. on Windows there is interaction with "wenviron").
Fortunately either putenv("A=") or putenv("A") will remove "A" from the
environment on these platforms.  On other platforms fall back to direct
manipulation of "environ".

Also add UnPutEnv to the API and add a test for the behavior of both.

Brad King 0c7029c642 Refactor CMake version handling
Move the CMake version number components out of "CMakeLists.txt" into
dedicated file "Source/CMakeVersion.cmake".  Set the TWEAK level to the
date explicitly.  Add a "Source/CMakeVersion.bash" script to update the
date, thus replacing KWSys DateStamp for CMake.  Teach the bootstrap
script to extract the version components from their new location.

Brad King 11d9b21126 Add cmGeneratorTarget to represent a target during generation
Some per-target information and logic is common to all generators.
Some of that information is currently stored in cmTarget but that
should be reserved for the configure step.  Create a class to hold
per-target information for generators.  On construction classify
sources from the target and store them in separate members.  This
classification is already implemented separately in each generator.

Brad King 5cd879c4e7 bootstrap: Convert MSYS paths to Windows format (#13001)
We set CMAKE_PREFIX_PATH from the --prefix= option.  The calling shell
might not translate "/c/..." to "c:/..." paths but we need to store
Windows paths in CMake cache variables.  Pass the specified path through
the MSYS shell in a form it will convert to a Windows path using the
MSYS fstab.

Some MSYS bash implementations leave trailing space on the command line
to 'cmd /c echo ...' after quoting the message.  The Windows echo tool
preserves both the quotes and the trailing space.  Use a sed expression
that strips quotes and trailing spaces after the end quote.

Brad King c19868b256 bootstrap: Forward options after '--' to cmake
Provide an interface simpler than --init= to set cache values during
bootstrap builds.  For example:

 ./bootstrap --system-zlib -- -DZLIB_ROOT=/opt/zlib

will configure CMake with a system zlib library and initialize ZLIB_ROOT
in the cache for use by FindZLIB.

Brad King 60d72b56ed bootstrap: Granular system library selection (#11431)
This adds the ability for packagers to specify that some libraries
should use system versions and others should use the CMake versions.

This allows a bit of flexibility and means Homebrew (an OSX package
manager) no longer has to continue to patch the CMake build process.

Brad King f20d091a2c Tru64: Place cmOStringStream vtable uniquely (#10541)
GCC places the vtable in the object implementing the first non-pure,

the location unique by putting the destructor in a single object file.

Brad King 5bfffd6f29 New version scheme to support branchy workflow
Prepare to switch to the workflow described by "git help workflows".  In
this workflow, the "master" branch is always used to integrate topics
ready for release.  Brand new work merges into a "next" branch instead.
We need a new versioning scheme to work this way because the version on
"master" must always increase.

We no longer use an even/odd minor number to distinguish releases from
development versions.  Since we still support cvs checkout of our source
tree we cannot depend on "git describe" to compute a version number
based on the history graph.  We can use the CCYYMMDD nightly date stamp
to get a monotonically increasing version component.

The new version format is "major.minor.patch.(tweak|date)".  Releases
use a tweak level in the half-open range [0,20000000), which is smaller
than any current or future date.  For tweak=0 we do not show the tweak
component, leaving the format "major.minor.patch" for most releases.
Development versions use date=CCYYMMDD for the tweak level.  The
major.minor.patch part of development versions on "master" always
matches the most recent release.

For example, a first-parent traversal of "master" might see

        v2.8.1      2.8.1.20100422    v2.8.2
           |              |              |
  ----o----o----o----o----o----o----o----o----

Since the date appears in the tweak component, the next release can
increment the patch level (or any more significant component) to be
greater than any version leading to it.  Topic branches not ready for
release are published only on "next" so we know that all versions on
master lead between two releases.

Brad King d2e1f2b4d6 Introduce "generator expressions" to add_test()
This introduces a new syntax called "generator expressions" to the test
COMMAND option of the add_test(NAME) command mode.  These expressions
have a syntax like $<TARGET_FILE:mytarget> and are evaluated during
build system generation.  This syntax allows per-configuration target
output files to be referenced in test commands and arguments.

Brad King fd10589995 ENH: Improve dynamic variable scope implementation
Previously each new variable scope (subdirectory or function call) in
the CMake language created a complete copy of the key->value definition
map.  This avoids the copy using transitive lookups up the scope stack.
Results of queries answered by parents are stored locally to maintain
locality of reference.

The class cmDefinitions replaces cmMakefile::DefinitionsMap, and is
aware of its enclosing scope.  Each scope stores only the definitions
set (or unset!) inside it relative to the enclosing scope.

Brad King 7797237629 BUG: Fix bootstrap for Debian Almquist Shell
The Debian Almquist Shell (dash) provides minimal POSIX compliance
instead of the power of bash.  It converts literal '\n' to a real
newline even in a single-quoted string.  This works around the problem
by avoiding the literal.  We can no longer use HEREDOC.

Brad King 776e21d1c7 COMP: Avoid String.c inclusion by Compaq templates
The Compaq compiler (on VMS) includes 'String.c' in source files that
use the stl string while looking for template definitions.  This was the
true cause of double-inclusion of the 'kwsysPrivate.h' header.  We work
around the problem by conditionally compiling the entire source file on
a condition only true when really building the source.

This moves code which generates ADD_TEST and SET_TESTS_PROPERTIES calls

cmScriptGenerator to get support for per-configuration script
generation (not yet enabled).

Brad King 98c51ff6dc ENH: Overhaul CMake version numbering
This moves the version numbers into an isolated configured header so
that not all of CMake needs to rebuild when the version changes.

Previously we had spaces, dashes and/or the word 'patch' randomly chosen
before the patch number.  Now we always report version numbers in the
traditional format "<major>.<minor>.<patch>[-rc<rc>]".

We still use odd minor numbers for development versions.  Now we also
use the CCYYMMDD date as the patch number of development versions, thus
allowing tests for exact CMake versions.

  - Make link type specific to library names without paths
    (name libfoo.a without path becomes -Wl,-Bstatic -lfoo)
  - Make directory ordering specific to a runtime path computation feature
    (look for conflicting SONAMEs instead of library names)
  - Implement proper rpath support on HP-UX and AIX.
