Brad King 86578eccf2 Simplify CMake per-source license notices
Per-source copyright/license notice headers that spell out copyright holder
names and years are hard to maintain and often out-of-date or plain wrong.
Precise contributor information is already maintained automatically by the
version control tool.  Ultimately it is the receiver of a file who is
responsible for determining its licensing status, and per-source notices are
merely a convenience.  Therefore it is simpler and more accurate for
each source to have a generic notice of the license name and references to
more detailed information on copyright holders and full license terms.

Our `Copyright.txt` file now contains a list of Contributors whose names
appeared source-level copyright notices.  It also references version control
history for more precise information.  Therefore we no longer need to spell
out the list of Contributors in each source file notice.

Replace CMake per-source copyright/license notice headers with a short
description of the license and links to `Copyright.txt` and online information
available from "https://cmake.org/licensing".  The online URL also handles
cases of modules being copied out of our source into other projects, so we
can drop our notices about replacing links with full license text.

Run the `Utilities/Scripts/filter-notices.bash` script to perform the majority
of the replacements mechanically.  Manually fix up shebang lines and trailing
newlines in a few files.  Manually update the notices in a few files that the
script does not handle.

Brad King 0ac18d40c8 Remove `//------...` horizontal separator comments
Modern editors provide plenty of ways to visually separate functions.
Drop the explicit comments that previously served this purpose.
Use the following command to automate the change:

    $ git ls-files -z -- \
        "*.c" "*.cc" "*.cpp" "*.cxx" "*.h" "*.hh" "*.hpp" "*.hxx" |
      egrep -z -v "^Source/cmCommandArgumentLexer\." |
      egrep -z -v "^Source/cmCommandArgumentParser(\.y|\.cxx|Tokens\.h)" |
      egrep -z -v "^Source/cmDependsJavaLexer\." |
      egrep -z -v "^Source/cmDependsJavaParser(\.y|\.cxx|Tokens\.h)" |
      egrep -z -v "^Source/cmExprLexer\." |
      egrep -z -v "^Source/cmExprParser(\.y|\.cxx|Tokens\.h)" |
      egrep -z -v "^Source/cmFortranLexer\." |
      egrep -z -v "^Source/cmFortranParser(\.y|\.cxx|Tokens\.h)" |
      egrep -z -v "^Source/cmListFileLexer\." |
      egrep -z -v "^Source/cm_sha2" |
      egrep -z -v "^Source/(kwsys|CursesDialog/form)/" |
      egrep -z -v "^Utilities/(KW|cm).*/" |
      xargs -0 sed -i '/^\(\/\/---*\|\/\*---*\*\/\)$/ {d;}'

This avoids modifying third-party sources and generated sources.

Brad King e1c7747253 Format include directive blocks and ordering with clang-format
Sort include directives within each block (separated by a blank line) in
lexicographic order (except to prioritize `sys/types.h` first).  First
run `clang-format` with the config file:

    ---
    SortIncludes: false
    ...

Commit the result temporarily.  Then run `clang-format` again with:

    ---
    SortIncludes: true
    IncludeCategories:
      - Regex:    'sys/types.h'
        Priority: -1
    ...

Commit the result temporarily.  Start a new branch and cherry-pick the
second commit.  Manually resolve conflicts to preserve indentation of
re-ordered includes.  This cleans up the include ordering without
changing any other style.

Use the following command to run `clang-format`:

    $ git ls-files -z -- \
        '*.c' '*.cc' '*.cpp' '*.cxx' '*.h' '*.hh' '*.hpp' '*.hxx' |
      egrep -z -v '(Lexer|Parser|ParserHelper)\.' |
      egrep -z -v '^Source/cm_sha2' |
      egrep -z -v '^Source/(kwsys|CursesDialog/form)/' |
      egrep -z -v '^Utilities/(KW|cm).*/' |
      egrep -z -v '^Tests/Module/GenerateExportHeader' |
      egrep -z -v '^Tests/RunCMake/CommandLine/cmake_depends/test_UTF-16LE.h' |
      xargs -0 clang-format -i

This selects source files that do not come from a third-party.

Brad King 84d124e8f0 Fix lookup of source names after conversion to their actual case (#15259)
Since commit v3.1.0-rc1~688^2~15 (cmTarget: Add a method to obtain list of
filenames for sources, 2014-03-17) we have code paths that lookup sources by
strings containing their own full path after normalization to the actual case
on disk.  This fails in the case that a cmSourceFile has already been created
with a different case in the filename.  The comparison of the directory works
because it is always normalized.  Only the comparison of the file name fails.

Fix this by using a case-insensitive comparison of source file names on
platforms that do not have case-sensitive filesystems.

Brad King 96afb12087 Convert CMake to OSI-approved BSD License
This converts the CMake license to a pure 3-clause OSI-approved BSD
License.  We drop the previous license clause requiring modified

cover the full development time range.

Brad King d800910efd BUG: Fix matching of ambiguous sf extensions.
A name with an ambiguous extension may only match an unambiguous name
that is extended by one of the fixed set of extensions tried when
finding the source file on disk.  This rule makes matching of source
files with ambiguous extensions much less aggressive but still
sufficient.

Brad King 0247a495c1 ENH: Recognize src extensions of all enabled langs
For historical reasons we still support naming of source files without
their extension.  Sources without known extensions are located on disk
by iterating through a fixed set of possible extensions.  We now want
users to always specify the extension, so the fixed set will not be
expanded and is preserved for compatibility with older projects.

This change adds recognition of extensions of all enabled languages to
avoid checking the disk for files whose extensions are unambiguous but
not in the original fixed set.

Brad King 35936433e1 ENH: Merging changes from branch CMake-SourceFile2-b between tags
CMake-SourceFile2-bp and CMake-SourceFile2-b-mp1 to trunk.  This
commit is surrounded by tags CMake-SourceFile2-b-mp1-pre and
CMake-SourceFile2-b-mp1-post on the trunk.

The changes re-implement cmSourceFile and the use of it to allow
instances to be created much earlier.  The use of cmSourceFileLocation
allows locating a source file referenced by a user to be much simpler
and more robust.  The two SetName methods are no longer needed so some
duplicate code has been removed.  The strange "SourceName" stuff is
gone.  Code that created cmSourceFile instances on the stack and then
sent them to cmMakefile::AddSource has been simplified and converted
to getting cmSourceFile instances from cmMakefile.  The CPluginAPI has
preserved the old API through a compatibility interface.

Source lists are gone.  Targets now get real instances of cmSourceFile
right away instead of storing a list of strings until the final pass.

TraceVSDependencies has been re-written to avoid the use of
SourceName.  It is now called TraceDependencies since it is not just
for VS.  It is now implemented with a helper object which makes the
code simpler.
