doxygen: maintain order of lines in doxyfile

javaw: make javadoc optional

msvc: add pdb_install_task with /DEBUG:* flags

See merge request !2224

Make javadoc optional to support builds on platforms that don't include
javadoc in their Java distribution.

This patch corrects an error in the exec_response_command exception
handler which always assumed that the execution's stdout would be bound
to the the WafError exception object.

However, this assumption is only true when the execution completes with
a non-zero status code. For other exceptions, the stdout attribute is
not bound.

Now, when stdout is not available, the WafError msg will be used
instead.

The order of the lines in a doxyfile are important. This patch uses an
ordered dictionary to keep the keys of the doxyfile in the same order.

This is particularly important for doxyfiles that contain @include
lines. In such cases, if the dictionary is not ordered, the @include
line can end up in the middle of the generated doxyfile and thus
override all entries that were seen before it.

Currently PDBs are only installed if the /DEBUG flag appears in the
current toolchain's LINKFLAGS attribute. This patch expands support
so that /DEBUG:FULL and /DEBUG:FASTLINK also cause PDBs to be
installed.

extras/syms: fix symbol regex on mac-o binaries

See merge request !2222

mac-o symbols are prefixed with an underscore. when specifying multiple
sub-regexes (e.g. 'sym1|sym2|sym3'), only the first will be matched
(since the expansion turns into '(?P<symbol>_?sym1|sym2|sym3)'). here,
this is remedied by wrapping the symbol regex in a paren group.

Utils: only use msys2 paths from msys2 python

See merge request !2217

This patch attempts to detects if, when we are running from within an
MSYS2 environement (MSYSTEM is set) we are also executing inside an
MSYS2 provided version of python. It does this by assuming that if we
are not in a cygwin environment and we are building on windows, If the
value of sys.executable is /usr/bin or /bin or /usr/local/bin (somethign
unixy) then we are running in an MSYS2 python interpreter and shoudl
compensate for msys2 root paths. Otherwise we shouldn't be doing extra
path manipulation.

TypeError: can only concatenate list

Not all tools executed by tasks support the '@argsfile' syntax for
shunting commandline arguments to a file. This means that if such
commands are shunted to a file early, he command will not work. On
windows the rc.exe command is such an example, but some tools on linux
have similar limitations. In the posix case, we artifically limit our
commandline size because it is difficult/variable to caluclate what the
actual limit is (it is partially dependent on environment size). This
could artifically cause commands to fail due to commandline length when
they otherwise wouldn't.

This patch fixes this issue by adding the 'allow_argsfile' flag to the
task. This way certain task instances will be able to specify if they
are compatible with the '@argsfile' syntax or not.

Address ntpath bug with empty prefix

See merge request !2215

This patch addresses the bug described in issue #2225 where in using
posix paths and an empty PREFIX value can result in files being
installed to the root of the drive specified by destdir instead of to
the desired prefix value.  This is a bug in the assumption that user
specified paths that are strings will contain directory separators that
match the target operating system.

task: calculate correct cmdline bytes

See merge request !2214

The previous patches to workaround
http://support.microsoft.com/kb/830473 drastically over estimated the
number of characters in commands by treating the repr() version of the
command array as a reasonable estimator of commandline length. This
caused commands attempt to write argsfiles before they should have.

The new calculation calculates the number characters in the command
array and adds the number of spaces that would be added by ' '.join(cmd)
this provides a much closer estimate of the commandline length.

This also limits the CLI-length on non windows platforms to 200kB. This
prevents us hitting the much larger argument limits on Linux/BSD/MacOS
platforms.

javaw: add quiet=True to ant_globs to suppress warnings of globbing in build

See merge request !2212

Most of the ant_globs used are explicitly and knowingly on build directory
(ie. javadoc, jar re) so the warning is quite spurious. The only one that
may be in doubt is the source re one: I added also here because if you use
a code generator (ie. protoc) then it is also correct to glob on builds and
the warning is misleading.
