Use an ordered dict for the compiler dictionary and sort it according
to a priority order: fortran, c, c++, etc.
This also ensures that builds are reproducible because it would be
a toss-up whether a C or a C++ compiler would be used based on the
order in which compilers.items() would return items.

The paths are already relative to the target dir.
Includes a test for this which generates and builds in subdirs. If all
the generation and usage is done in the build root, this bug will
obviously not be triggered.
An empty / no-op dependency can be expressed as []. This works with
the dependencies kwarg in executable targets such as shared_library,
but now with declare_dependency, where it would error out with
"error: Dependencies must be external deps" because the deps are
not flattened in this case. This patch fixes that.
Fixes#1500
and column are printed out by other parser code.
Add a print of the line with the error, and where on the line the error
occurred.
Add a print of where the block scope started, if the error is due to
missing the block scope end token.
Special wrap modes:
nofallback: Don't download wraps for dependency() fallbacks
nodownload: Don't download wraps for all subproject() calls
Subprojects are used for two purposes:
1. To download and build dependencies by using .wrap files if they
are not provided by the system. This is usually expressed via
dependency(..., fallback: ...).
2. To download and build 'copylibs' which are meant to be used by
copying into your project. This is always done with an explicit
subproject() call.
--wrap-mode=nofallback will never do (1)
--wrap-mode=nodownload will do neither (1) nor (2)
If you are building from a release tarball, you should be able to
safely use 'nodownload' since upstream is expected to ship all
required sources with the tarball.
If you are building from a git repository, you will want to use
'nofallback' so that any 'copylib' wraps will be download as
subprojects.
Note that these options do not affect subprojects that are git
submodules since those are only usable in git repositories, and you
almost always want to download them.
This will benefit projects such as GNOME Recipes that prefer using
submodules over wraps because it's easier to maintain since git is
aware of it, and because it integrates with their existing
workflow. Without this, these projects have to manually initialize
the submodules which is completely unnecessary.

Also use a pathlib.Path object for the checks since it does I/O only
once and is much more efficient anyway. Path objects are available
since Python 3.4, so this is fine.
Besides fixing output capture, it also fixes a strange bug in MSBuild
where if the command list is too long, it will remove random
characters from the command list before passing it to the command.

For newer VS versions, we can simply rely on 'VisualStudioVersion' being
set in the environment.
For VS2010, we fall back to check 'VSINSTALLDIR' for the version string.
If the backend can not be auto detected, we raise an exception to make the
user choose an explicit backend.
We also print the detected backend to the meson log.
We were adding them to the CompilerArgs instance in the order in which
they are specified, which is wrong because later dependencies would
override previous ones. Add them in the reverse order instead.

VS2017 requires the 'WindowsTargetPlatformVersion' property to be set.
We gather the version to use from the environment variable
'WindowsSDKVersion' that will be set by the VS developer command prompt.
VS2015 automatically picks up outputs from CustomBuild commands, which we
now use instead of CustomBuildStep commands, which do not get picked up
automatically.
This changes how generated files are added to the VS project.
Previously, they were all added as a single CustomBuildStep with all
generator commands, inputs and outputs merged together.
Now, each input file is added separately to the project and is given a
CustomBuild command. This adds all generator input files to the files list
in the VS gui and allows to run only some of the generator commands if
only some of the input files have changed.
We check for the existence of PDB files in the install script, so we
don't need to do all this mucking about here. That's more robust too
because we don't need to parse build arguments in buildtype=plain
and decide if the PDB file would be generated.
There is no need to do obj.get_command() and in fact it's wrong
because the VS backends need to resolve each object to absolute paths
and get_command() does not do that.
This should fix invocation of GNOME module helpers with the VS backends
For the record, absolute paths for programs are needed because the
same PATH environment won't necessarily be available to Visual Studio
when it builds the generated solution.

This used to produce a warning, but then would crash anyway. It's
simpler if we just error out and have the user disable gir generation or
install gobject-introspection.
