daily update

Fix races in gdb.base/pr10179.exp.

Revert "elfread.c (elf_symtab_read): Stop memory leak"

It turns out that this change is not correct, and it causes a crash
on sparc-solaris while trying to load ld.so.  This is because the
memory is actually still referenced after elf_symtab_read completes.

gdb/ChangeLog:

        * elfread.c (elf_symtab_read): Revert the previous change
        that tried to stop a memory leak.

Fix uses of litteral `GDB' in `In Memoriam' appendix.

@value{GDBN} should be used in place of GDB, so this patch fixes it.

gdb/doc/ChangeLog:

        * gdb.texinfo (In Memoriam): Replace litteral uses of `GDB' with
        `@value{GDBN}'.
