Fix ttyslot namespace (bug 18547).
ttyslot (XPG4) calls the non-XPG4 functions endttyent, getttyent and
setttyent, which in turn bring in references to fgets_unlocked and
getttynam. This patch fixes this by making these functions into weak
aliases and calling the __* names as needed.
Tested for x86_64 and x86 (testsuite, and that disassembly of
installed stripped shared libraries is unchanged by the patch).
[BZ #18547]
* misc/getttyent.c (getttynam): Rename to __getttynam and define
as weak alias of __getttynam. Use prototype function definition.
Call __setttyent, __getttyent and __endttyent instead of
setttyent, getttyent and endttyent.
(getttyent): Rename to __getttyent and define as weak alias of
__getttyent. Call __setttyent instead of setttyent. Call
__fgets_unlocked instead of fgets_unlocked.
(setttyent): Rename to __setttyent and define as weak alias of
__setttyent.
(endttyent): Rename to __endttyent and define as weak alias of
__endttyent.
* include/ttyent.h (__getttyent): Declare. Use libc_hidden_proto.
(__setttyent): Likewise.
(__endttyent): Likewise.
(getttyent): Don't use libc_hidden_proto.
(setttyent): Likewise.
(endttyent): Likewise.
* misc/ttyslot.c (ttyslot): Call __setttyent, __getttyent and
__endttyent instead of setttyent, getttyent and endttyent.
* conform/Makefile (test-xfail-XPG4/unistd.h/linknamespace):
Remove variable.
