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.

* select.cc (cygwin_select): Make degenerate case cancelable.
(select_stuff::destroy): New inline method to delete memory taken
by select_stuff.
(select_stuff::~select_stuff): Call destroy.
(select_stuff::wait): Add case to allow canceling select.
* select.h (select_stuff::destroy): Declare.
* thread.cc: Mark poll, pselect and poll as cancelable.
