This isn't useful yet because we currently only have dependencies for
C/C++ targets (the rest all use link deps), but we will need this for
Vala, Rust, and more.
get_filename() made no sense for CustomTarget since it can have multiple
outputs. Also use get_outputs() for GeneratedList since it has the same
meaning and remove unused set_generated().
As a side-effect, we now install all the outputs of a CustomTarget.
This is done by adding a new compiler method called 'no_warn_args' which
returns the argument(s) required for the compiler to emit no warnings
for that compilation.
This take care of not disabling warnings for C code compiled into the
BuildTarget. Also includes tests for ensuring all this.

With C/C++, on Windows you don't need to pass any arguments for a static
library to be PIC. On UNIX platforms you need to pass -fPIC.
Other languages such as D have compiler-specific PIC arguments required
for PIC support in static libraries on UNIX platforms.
This kwarg allows people to specify which static libraries should be
built with PIC support. This is usually used for static libraries that
will be linked into shared libraries.
Otherwise they are built regardless of whether they are actually used by
anything else. Only build them if they're going to be installed or
always-built.
Ideally, we should also do this with all BuildTargets, and provide
a mechanism for people to specify which targets they want built with
'all', and a way for people to add them to custom targets.. Without
this, things like tests and examples are *always* built with no way to
turn that off.
For now, we just do this because it also with tests that check for
dependency issues. Including all CustomTargets in `all` results in
dangling targets to also be built, which hides the problem and makes it
racy.
self.dep_rules is not set anywhere by anything, so this code always
results in a no-op. If it didn't result in a no-op, it would need to be
seriously rewritten because it has bitrotten and makes no sense anymore.
This is definitely more correct since it takes into account the
cross-compilation status. We also now do the Java and CSharp sanity
checks on the BuildTarget level instead of in the Ninja backend.
Because we were iterating over all generated sources of a target in one
go, we weren't adding the correct header_deps for generated source
compiles. We need to aggregate the header_deps first before generating
source compile targets for generated source files.
For commands that always output to stdout and don't have a "-o" or
"--output" or some other similar option, this 'capture' setting allows
the build to capture the result and place it in the output file.
Target-specific compiler options should be split into pre-processor
defines, include directories, and additional options, then
escaped/quoted and added to the appropriate portions of the project
file.
The "115 spaces backslash" test now checks that backslashes and spaces
now work properly in all three places.
Trivially correct typo fix. Didn't actually break anything because the
fallback is libdir anyway, and we always install static libraries to
libdir.
