If legacy implementations are generated, eolian_gen now creates
a separate file for them and includes it. The file name convention
for that is <.c file name without ext>.legacy.<.c file name ext>
or <.c file name>.legacy.c if it has no ext, so for example
foo.eo.c becomes foo.eo.legacy.c and foo becomes foo.legacy.c.
The file is generated assuming there are any legacy APIs contained
inside the .eo file.
By default, dependency files are now generated only for headers.
This makes sense for the C generator and our dependency tracking
needs. If full dependencies are needed, there is now the 'D'
output, which has the old behavior.
It is now possible to generate a separate .d file which will
contain Make-style dependencies for the files generated in that
batch, i.e. if you geerate header, legacy header and source, the
.eo.d file will contain dependency lists for those three.
It should be possible to integrate this into our build system to
enable proper regeneration of .eo files in an incremental manner.
Fixes T2251.
Doc refs no longer introduce new dependencies into files. Instead,
they're parsed globally, and any doc ref lookup is also made
globally. This allows unit based dependencies to correspond more
to what files actually really need at compile time/runtime, with
docs being irrelevant to that; it also simplifies the API.
The doc resolution API now takes Eolian_State instead of
Eolian_Unit, too.
As it is no longer necessary to pass unit when evaluating exprs,
it is not necessary to pass it here either. Convert all the APIs
to the new style and update all instances in our tree.
Previously the output base name used to include extension, now
you don't need to specify an extension and it's determined from
the input file name instead.
Also, implementation boilerplate used to merge with .eo.c before,
which made no sense. Now it's merged with .c instead when it
exists or makes a new .c file when it doesn't.
If you specify type-explicit output filename, this automatically
adds it so that it's generated even without specifying -gT.
This is meant to help user friendliness. Also add a note about
this to help listing.
This allows generators to silence type errors in validation in order
to reduce duplicate error messages when generating multiple files.
Also adjusted the C generator to only emit type errors when generating
Eo header files.

It's now generalized to work properly with legacy functions
as well as correctly append suffixes. Thus, it can be easily
used with the documentation generator and in other places.
