This introduces a few missing NULL-checks in public functions, and
align their docstrings with real behavior by getting rid of copy-paste
mistakes.

As discussed with Rusty Russel, it would be nice to remove the related
code from kernel. Deprecate its use on kmod, so people know they
shouldn't be using it.
Search modules.builtin file before saying the module was not found.
Note: these "modules" should not appear as dependencies of other modules
(in modules.dep) even if they appear in modinfo. This fixes the return
code of modprobe with builtin modules.
Also fixes a small coding style issue in module_is_inkernel().
This allows us to prepend an arbitrary item to the PATH environment
variable, meaning we can favor the binaries we just built, rather than
relying on those in the filesystem.
test 1 - check whether modprobe outputs the right thing when
using --show-depends is used with already loaded modules.
test 2 - check whether modprobe outputs the right thing when
using --show-depends with modules not loaded yet
Provide a function to dump the index files to a certain fd. It could be
more optimized (particularly the functions to dump the index that were
copied and pasted from m-i-t), but it seems like the only user of it is
'modprobe -c', used for debugging purposes. So, keep it as is.
Now with './tools/modprobe --show-depends ahci' (ahci is builtin) we have the following
output:
$ ./tools/modprobe --show-depends ahci
builtin ahci
Just like modprobe from m-i-t. Previously we had:
$ ./tools/modprobe --show-depends ahci
FATAL: Module ahci not found.
Uses kmod_elf_get_dependency_symbols() that looks into ".symtab" for
UNDEF symbols and matches the name from ".strtab" to "__versions" to
get crc.
Likely the public API should unify the symbol information getters and
list release, they are almost the same.
