Since nobody had made any changes to i386v-nat.c on sourceware since
the repository was started, we were still getting the version from the
vendor branch. (If you don't understand how the vendor branch works,
treasure your innocence.) I naively assumed that, to see what changes
had been introduced in version 1.2, one should diff it with 1.1,
as they say in TV Guide, "with hilarious results".
This change simply restores i386v-nat.c to what it used to be before I
started bungling around. The text of this revision should be
identical to that of revision 1.1.1.3, which was the former head of
the trunk. (Yes, 1.1.1.3 was the head of the trunk. As I said,
treasure your innocence.)

* objfiles.c (free_objfile): Don't call CLEAR_SOLIB, and don't
detach the core target. These tasks are taken care of elsewhere.
* target.c (remove_target_sections): New function.
* target.h (remove_target_sections): New declaration.
* solib.c (symbol_add_stub): Check whether we've already created
an objfile for this shared object first, before doing all that
work to compute section addresses, etc.
* objfiles.c (unlink_objfile): Report an internal error if objfile
doesn't occur in the object_files list.
* solib.c (special_symbol_handling): Delete argument; it's not
used.
* solib.c (SOLIB_EXTRACT_ADDRESS): New macro to extract addresses
from solib structures. Use it throughout solib.c, get rid of all
CORE_ADDR casts.
(struct so_list): Change type of lmaddr to CORE_ADDR.
(first_link_map_member): Change return value type to CORE_ADDR,
update callers.
(solib_add_common_symbols): Change parameter type to CORE_ADDR,
update callers.
(open_symbol_file_object, find_solib): Change type of lm variable
to CORE_ADDR.
(dos_print_tty_state, dos_info, _initialize_ser_dos): Convert
to ISO C. Use ATTRIBUTE_UNUSED to avoid compiler warnings.
(dos_info): Avoid compiler warning when printing a ptrdiff_t.
