[PATCH] GLIBC_PRIVATE

[Jakub Jelinek <jakub at redhat dot com>]

Hi!

The following patch moves internal glibc symbols to GLIBC_PRIVATE symbol
version. Glibc bootstrap is still running, I'm posting this just to hear
feedback if you find any symbols which aren't actually private but are
marked so, or if you come up with symbols which aren't marked as private by
this patch although they are.
Symbols which are questionable (and not marked private in this patch):
__libc_allocate_rtsig
__libc_calloc
__libc_free
__libc_freeres
__libc_init_first
__libc_mallinfo
__libc_malloc
__libc_mallopt
__libc_memalign
__libc_pvalloc
__libc_realloc
__libc_sa_len
__libc_valloc
__free_fdresult
__nis_default_access
__nis_default_group
__nis_default_owner
__nis_default_ttl
__nis_finddirectory
__nis_hash
__nisbind_connect
__nisbind_create
__nisbind_destroy
__nisbind_next
__nss_database_lookup
__nss_group_lookup
__nss_hostname_digits_dots
__nss_hosts_lookup
__nss_next
__nss_passwd_lookup
_dl_mcount_wrapper
_nl_default_dirname
_nl_domain_bindings
_nl_msg_cat_cntr

Symbols which are questionable but I've marked them private in the patch:
_dl_debug_initialize
_dl_debug_state
