This is important so people can not trick Meson to select a
subproject_dir that is not in the project's source directory.
It also ensures a string is used for the path.
They now are published by the D Language Foundation, and not Digital
Mars. Therefore, their signature has changed slightly.
(We can not check for 'DMD', because that string appears in every
compiler version output to denote the frontend version used by the
compiler).
The previous change disallowed any subdirectories for subproject dirs,
and therefore broke a couple of projects making use of that.
This change still prevents people from setting subproject dirs that are
not in the project's source tree, while allowing to specify any path
within the project's directory again.
Resolves: #2719
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.

Also, use '^' to escape newlines in appveyor-install.bat to avoid an
absurdly long line, remove some unnecessary quotation, and alphabetically
sort packages
Also, define the _XOPEN_SOURCE feature test macro in the boost test to avoid
'not declared in this scope' warnings for pthread_rwlock_init(), etc.
teach detect_meson_py_location() that meson.py is not the
only one meson executable (there's wraptool + legacy scripts)
that could be installed to the PATH folder
fixes#2810
This already reports the location (in a slightly different format), but
using mlog.warning() will make it easier if we want to change the location
format in future.
