......................................................................
Introduce partial_symtab::read_symtab method
This introduces a new partial_symtab::read_symtab method, and updates
the symbol readers to subclass partial_symtab and implement this
method. The old read_symtab and read_symtab_private members are
removed.
In practice, only DWARF and CTF are truly updated to take advantage of
the new setup. The other symbol readers are less actively maintained,
and so this patch also introduces a "legacy_psymtab", which
essentially works the same way as the old partial_symtab.
(Note that, without more knowledge of the interaction between these
symbol readers, fixing this to remove the new (small) overhead is not
trivial, because these readers copy the read_symtab pointer between
partial symtabs.)
