Brad King b5ec5b0901 Avoid using KWSys auto_ptr by adopting it ourselves
Replace use of cmsys::auto_ptr with a CM_AUTO_PTR macro that maps to
our own implementation adopted from the KWSys auto_ptr implementation.
Later we may be able to map CM_AUTO_PTR to std::auto_ptr on compilers
that do not warn about it.

Automate the client site conversions:

    git grep -l auto_ptr -- Source/ | grep -v Source/kwsys/ | xargs sed -i \
      's|cmsys::auto_ptr|CM_AUTO_PTR|;s|cmsys/auto_ptr.hxx|cm_auto_ptr.hxx|'

Extend link commands by running `ldd -u -r` to detect shared

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 64b5520346 Isolate formatted streaming blocks with clang-format off/on
The clang-format tool can do a good job formatting most code, but
well-organized streaming blocks are best left manually formatted.

Find blocks of the form

    os <<
      "...\n"
      "...\n"
      ;

using the command

    $ git ls-files -z -- Source |
      egrep -v -z '^Source/kwsys/' |
      xargs -0 pcregrep -M --color=always -B 1 -A 1 -n \
        '<<[^\n]*\n(^ *("[^\n]*("|<<|;)$|;)\n){2,}'

Find blocks of the form

    os << "...\n"
       << "...\n"
       << "...\n";

using the command

    $ git ls-files -z -- Source |
      egrep -v -z '^Source/kwsys/' |
      xargs -0 pcregrep -M --color=always -B 1 -A 1 -n \
        '<<[^\n]*\n(^ *<<[^\n]*(\\n"|<<|;)$\n){2,}'

Surround such blocks with the pair

    /* clang-format off */
    ...
    /* clang-format on */

in order to protect them from update by clang-format.  Use the C-style
`/*...*/` comments instead of C++-style `//...` comments in order to
prevent them from ever being swallowed by re-formatting of surrounding
comments.

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.

Daniel Pfeifer 04d74a7f89 Clang-Tidy: copy stdout to sterr; ignore original stderr
Clang-Tidy writes the number of warnings, the number of suppressed
warnings, and instructions on how to suppress warnings to stderr.  Since
each source file is checked individually, this repetitive information is
disturbing and should be suppressed.

The actual warning messages are written to stdout.  Some IDEs (eg.
QtCreator) analyze only stderr for issues.  Redirecting Clang-Tidy's
stdout to stderr makes sure the warnings are correctly displayed.

Brad King c5eb21b6d1 Fix dependency scanning configuration in subdirectories
Refactoring in commit v3.5.0-rc1~347^2~2 (Set the current dirs on the
snapshot before creating the cmMakefile) accidentally changed the
source and binary directories configured in `cmake -E cmake_depends`
for use during dependency scanning.  This can cause the wrong directory
information to be loaded.  It also breaks Fortran module dependency
scanning for modules provided by targets in subdirectories that do
not have Fortran_MODULE_DIRECTORY set.

Fix the dependency scanning directory configuration and add a test to
cover the Fortran module case in which the breakage was observed.

Brad King 1787269ef3 cmake: Fix `-E time` argument passing to child
Since this command was introduced in 2002 it has incorrectly constructed
the child process command line by concatenating arguments separated by
spaces with no quoting.  Fix this by passing the command argument vector
directly to RunSingleCommand without an intermediate quoting and
re-parsing step.

cmJoin is cumbersome to use in cases where the objective is to

case, the joiner string is harder to read and reason about.  cmWrap
aims to solve that.

Provide an overload taking char wrappers to simplify the case
of surrounding every element in quotes without needing to escape
the quote character.
