posix: Sync glob with gnulib [BZ #1062]
This patch syncs posix/glob.c implementation with gnulib version
b5ec983 (glob: simplify symlink detection). The only difference
to gnulib code is
* DT_UNKNOWN, DT_DIR, and DT_LNK definition in the case there
were not already defined. Gnulib code which uses
HAVE_STRUCT_DIRENT_D_TYPE will redefine them wrongly because
GLIBC does not define HAVE_STRUCT_DIRENT_D_TYPE. Instead
the patch check for each definition instead.
Also, the patch requires additional globfree and globfree64 files
for compatibility version on some architectures. Also the code
simplification leads to not macro simplification (not need for
NO_GLOB_PATTERN_P anymore).
Checked on x86_64-linux-gnu and on a build using build-many-glibcs.py
for all major architectures.
[BZ #1062]
* posix/Makefile (routines): Add globfree, globfree64, and
glob_pattern_p.
* posix/flexmember.h: New file.
* posix/glob_internal.h: Likewise.
* posix/glob_pattern_p.c: Likewise.
* posix/globfree.c: Likewise.
* posix/globfree64.c: Likewise.
* sysdeps/gnu/globfree64.c: Likewise.
* sysdeps/unix/sysv/linux/alpha/globfree.c: Likewise.
* sysdeps/unix/sysv/linux/mips/mips64/n64/globfree64.c: Likewise.
* sysdeps/unix/sysv/linux/oldglob.c: Likewise.
* sysdeps/unix/sysv/linux/wordsize-64/globfree64.c: Likewise.
* sysdeps/unix/sysv/linux/x86_64/x32/globfree.c: Likewise.
* sysdeps/wordsize-64/globfree.c: Likewise.
* sysdeps/wordsize-64/globfree64.c: Likewise.
* posix/glob.c (HAVE_CONFIG_H): Use !_LIBC instead.
[NDEBUG): Remove comments.
(GLOB_ONLY_P, _AMIGA, VMS): Remove define.
(dirent_type): New type. Use uint_fast8_t not
uint8_t, as C99 does not require uint8_t.
(DT_UNKNOWN, DT_DIR, DT_LNK): New macros.
(struct readdir_result): Use dirent_type. Do not define skip_entry
unless it is needed; this saves a byte on platforms lacking d_ino.
(readdir_result_type, readdir_result_skip_entry):
New functions, replacing ...
(readdir_result_might_be_symlink, readdir_result_might_be_dir):
these functions, which were removed. This makes the callers
easier to read. All callers changed.
(D_INO_TO_RESULT): Now empty if there is no d_ino.
(size_add_wrapv, glob_use_alloca): New static functions.
(glob, glob_in_dir): Check for size_t overflow in several places,
and fix some size_t checks that were not quite right.
Remove old code using SHELL since Bash no longer
uses this.
(glob, prefix_array): Separate MS code better.
(glob_in_dir): Remove old Amiga and VMS code.
(globfree, __glob_pattern_type, __glob_pattern_p): Move to
separate files.
(glob_in_dir): Do not rely on undefined behavior in accessing
struct members beyond their bounds. Use a flexible array member
instead
(link_stat): Rename from link_exists2_p and return -1/0 instead of
0/1. Caller changed.
(glob): Fix memory leaks.
* posix/glob64 (globfree64): Move to separate file.
* sysdeps/gnu/glob64.c (NO_GLOB_PATTERN_P): Remove define.
(globfree64): Remove hidden alias.
* sysdeps/unix/sysv/linux/Makefile (sysdeps_routines): Add
oldglob.
* sysdeps/unix/sysv/linux/alpha/glob.c (__new_globfree): Move to
separate file.
* sysdeps/unix/sysv/linux/i386/glob64.c (NO_GLOB_PATTERN_P): Remove
define.
Move compat code to separate file.
* sysdeps/wordsize-64/glob.c (globfree): Move definitions to
separate file.

i386: Hide __old_glob64 [BZ #18822]
Hide internal __old_glob64 function to allow direct access within
libc.so and libc.a without using GOT nor PLT.
[BZ #18822]
* sysdeps/unix/sysv/linux/i386/glob64.c (__old_glob64): Add
libc_hidden_proto and libc_hidden_def.
