gdb: Move read_dbx_symtab to stabsread, and rename to read_stabs_symtab

Despite the name, read_dbx_symtab is not only used for the dbx file
format (also called the aout format). It is used by elf and coff
implicitly as well. So I think it makes more sense to have this function
in the generic stabsread file, so that reading elf files or coff files
depends less on GDB's ability to read dbx files.

There were 11 static functions in dbxread that were onlyl helper
functions, they were moved and kept as static in stabsread.c. Notably,
dbx_read_symtab - which is installed as a callback on legacy_psymtab
for aout, elf and coff at least - has been moved to stabsread.c and
renamed as well; the function that is specific to aout is
dbx_symfile_read, and that hasn't been moved.

Some macros had to be moved as well, but since they are still used
in dbxread, they were moved to the .h file that the struct symloc
is declared, so anyone can properly use the struct.
