Add locking when reading BFD sections
This adds some per-BFD locking to gdb_bfd_map_section and
gdb_bfd_get_full_section_contents.
It turned out that the background DWARF reader could race with the
auto-load code, because the reader might try to mmap a section when
the main thread was trying to read in .debug_gdb_scripts.
The current BFD threading model is that only BFD globals will be
locked, so any multi-threaded use of a BFD has to be handled specially
by the application.
