in string.h and strings.h. This caught unguarded string ops in
libc/inet/ethers.c __ether_line_w() function.
I will wait for fallout reports for a week or so,
then continue converting more libc_hidden_proto's.

* extra/locale/gen_wc8bit.c: use strrchr to parse locale
name to handle the case in which it contains a '.' character
like ANSI_X3.4-1968
* include/locale.h: use __UCLIBC_HAS_XLOCALE__ to control
inclusion of xlocale.h only
* libc/misc/ctype/ctype.c: add missing weak_alias for
__tolower_l and __toupper_l
* libc/misc/locale/locale.c: use strcasecmp (case insensitive)
for utf-8 locale name.

rather than the public weak ones so that the libc->libpthread forwarding code is able to work properly
this should fix the case where libpthread.so is not linked directly, but rather via another library:
app -> links to libfoo.so -> links to libpthread.so
and any function (like readdir_r) that does:
__UCLIBC_MUTEX_LOCK()
__UCLIBC_MUTEX_UNLOCK()

for 2.4 kernels.

returns NULL (the buffer contents is undefined);
also check errno more thoroughly (bugs were seen slipping through)

It is "make install_kernel_headers" now.

No mass migration of libc_hidden_proto(foo) planned.
Lets wait for potential fallout first.

Now it uses dedicated script instead of inline makefile commands,
which helps readability.
It also installs asm[-generic] and linux subdirs from kernel headers
(previously it had to be done separately).
Lastly, it passes each uclibc header thru unifdef, which strips
#ifdef UCLIBC_INTERNAL conditional from headers.
Currently it's a no-op (no such #ifders in tree).
The plan is to have libc_hidden_proto(foo) migrated to headers
and guard them by these #ifdefs.
