Because vala is not listed in clike_langs, is_source(fname) is returning False
for Vala source files. Therefore, extract_all_objects() is completely empty
for Vala programs.
Fixes#791
We missed one particular edge-case in #2413: when the generated vala
file is inside --basedir, the path is not just the basename.c
Since this case can never happen in a project test, this includes a unit
test for the same.

Non-GObject-based libraries are not (reliably) introspectable, and this only
happens to work by accident, at the moment.
Briefly: In non-libtool mode, g-ir-scanner inspects the run-time
dependencies of a generated executable to determine the shared library name
an -l flag corresponds to. But this generated executable only references
the libraries by *_get_type() functions. So, if the library doesn't contain
any Gobject-based types, it is not referenced, and this inspection fails
with PECOFF binaries. It seems that distutils doesn't currently decide to
use --as-needed, so this just happens to work on ELF.
g-ir-scanner --no-libtool needed some fixes similar to [1] for Cygwin, as
well. Now that is done, it's possible to make these tests run and pass on
Cygwin.

We were doing this on the basis of an old comment, but there was no
test for it and I couldn't reproduce the issue with clang on Linux
at all.
Let's add a (somewhat comprehensive) test and see if it breaks
anywhere if we stop doing this.
Halves the size of gstreamer's build.ninja from 20M to 8.7M

You can now pass a list of strings to the install_dir: kwarg to
build_target and custom_target.
Custom Targets:
===============
Allows you to specify the installation directory for each
corresponding output. For example:
custom_target('different-install-dirs',
output : ['first.file', 'second.file'],
...
install : true,
install_dir : ['somedir', 'otherdir])
This would install first.file to somedir and second.file to otherdir.
If only one install_dir is provided, all outputs are installed there
(same behaviour as before).
To only install some outputs, pass `false` for the outputs that you
don't want installed. For example:
custom_target('only-install-second',
output : ['first.file', 'second.file'],
...
install : true,
install_dir : [false, 'otherdir])
This would install second.file to otherdir and not install first.file.
Build Targets:
==============
With build_target() (which includes executable(), library(), etc),
usually there is only one primary output. However some types of
targets have multiple outputs.
For example, while generating Vala libraries, valac also generates
a header and a .vapi file both of which often need to be installed.
This allows you to specify installation directories for those too.
# This will only install the library (same as before)
shared_library('somevalalib', 'somesource.vala',
...
install : true)
# This will install the library, the header, and the vapi into the
# respective directories
shared_library('somevalalib', 'somesource.vala',
...
install : true,
install_dir : ['libdir', 'incdir', 'vapidir'])
# This will install the library into the default libdir and
# everything else into the specified directories
shared_library('somevalalib', 'somesource.vala',
...
install : true,
install_dir : [true, 'incdir', 'vapidir'])
# This will NOT install the library, and will install everything
# else into the specified directories
shared_library('somevalalib', 'somesource.vala',
...
install : true,
install_dir : [false, 'incdir', 'vapidir'])
true/false can also be used for secondary outputs in the same way.
Valac can also generate a GIR file for libraries when the `vala_gir:`
keyword argument is passed to library(). In that case, `install_dir:`
must be given a list with four elements, one for each output.
Includes tests for all these.

To use these, you just need to add the .vapi file to your target as
a source.
This test specifically tests that hand-written vapis referring to
C headers work.
Test that the --target-glib= argument while compiling Vala files is set
properly by using a feature (GtkTemplate) that requires glib >=2.38.
At the same time, also test that the appropriate gresource arguments are
also set for Vala targets. For each gresource.xml that is compiled, we
must pass --gresources=path/to/gresource.xml to valac.
With current Meson, this fails to configure with the following error:
Duplicate output 'dependency-generated/enum-types.h' from
'CustomTarget' 'enum-types.h'; conflicts with
'dependency-generated/enum-types.h' from 'CustomTarget'
'enum-types.h'
Move CCompiler.compile to Compiler.compile so that ValaCompiler can use
it. Also rewrite ValaCompiler.sanity_check to use it since it does
a simple compile check.
At the same time, it enhances ExternalLibrary to support arguments for
languages other than C-like.
Includes a test for this that links against zlib through Vala.
Closes#983
Since Vala require 'glib-2.0' and 'gobject-2.0' dependencies, it's
better to fail at 'valac' step with meaningful error.
Add missing 'gobject-2.0' dependency on the mixed source test case.
Not only does extract_all_objects() now work properly again,
extract_objects() also works if you specify a subset of sources all of
which have been compiled into a single unified object.
So, for instance, this allows you to extract all the objects
corresponding to the C sources compiled into a target consisting of
C and C++ sources.
This is the first step in making Vala support have feature-parity with
C/C++ support. Vala and Vapi sources generated with Generators and
CustomTargets are no longer ignored. Dependencies are setup properly and
they are added to the commandline.
