To maintain backward compatibility we cannot add recursive objects by
default. Print a warning when there are recursive objects to be pulled
and the argument is not set. After a while we'll do pull recursive
objects by default.
This adds a new method, partial_dependency to all dependencies. These
sub dependencies are copies of the original dependency, but with one or
more of the attributes replaced with an empty list. This allows creating
a sub dependency that has only cflags or drops link_arguments, for
example.
The added format argument for configure_file allows to specify the kind of
file that is treated. It defaults to 'meson', but can also have the 'cmake'
or 'cmake@' value to treat config.h.in files in the cmake format with #cmakedefine
statements.
Sometimes it is needed to run the current compiler with specific options
not to compile a file but rather to obtain additional info. For example,
GCC has several -print-* options to query it about the paths to
different libraries and development files. One use case is to get the
location of development files for GCC plugins, which is not easily
obtainable by other means:
gcc -print-file-name=plugin
For this purpose, it would be convenient if the compiler object returned
by meson.get_compiler(lang) could be used in run_command() directly.
This commit implements it.

The documentation doesn't require it and the interpreter code works around the
possibility of it being None. The ninja backend code however fails with
File "/home/whot/code/meson/mesonbuild/backend/ninjabackend.py", line 796, in generate_data_install
dstabs = os.path.join(subdir or None, plain_f)
File "/usr/lib64/python3.6/posixpath.py", line 78, in join
a = os.fspath(a)
TypeError: expected str, bytes or os.PathLike object, not NoneType
If install_dir is missing, default to datadir/projectname
After PR #2662, running test case common/125 shared module/ on Cygwin gets
me:
$ ninja -C _build
ninja: Entering directory `_build'
[7/7] Linking target prog.exe.
/usr/lib/gcc/x86_64-pc-cygwin/6.4.0/../../../../x86_64-pc-cygwin/bin/ld: warning: --export-dynamic is not supported for PE+ targets, did you mean --export-all-symbols?
Also, fix doc for correct version of first apperance.
Future work: Notwithstanding the hint that ld gives, these options are not
equivalent, and it's not clear we should be using it here:
--export-all-symbols is the default behaviour, and if the exports are
restricted by explicit annotations or a .def file, this option might be
overriding that...
Meson is able to redefine variables when retrieving them from
`pkg-config` dependencies. However, the documentation is missing.
This patch adds documentation for this feature.
