Don't try to be smart by dynamically realloc buffersize as it doesn't
work. Instead, be simple and allocate a buffer big enough.
This fixes a memory leak when calling getserv{ent,byname,byport}
multiple times.
To save memory we reduce number of max aliases. We seldomly will need
more than 1 anyways. While here, fix segfault that happened if there
were too many aliases.

This fixes issue introduced by 72e1a1ce186c39f07282398e2af9eb0253e60f15
This should also fix the following testcase to exit with error rather
than cause an endless loop.
int main(void) {
if (getservbyname("non-existing", "udp") == NULL)
err(1, "getservbyname");
return 0;
}

Some of the code is functionally identical before and after, but for now
I'm just mechanically reverting the entire mess.

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.

replace "buf = malloc(BUFSIZ); if (!buf) abort();" by __uc_malloc
elsewhere.
With last 7 patches together uclibc has 3k of static data total
with fairly big .config and with 2k being used for 2 x BUFSIZ stdio buffer:

total data 593

things, and avoid potential deadlocks caused when a thread holding a uClibc
internal lock get canceled and terminates without releasing the lock. This
change also provides a single place, bits/uClibc_mutex.h, for thread libraries
to modify to change all instances of internal locking.

instead. Based on an initial patch from Tobias Anderberg, but reworked. I
asked Tobias to look into doing something more like what is done in busybox,
but that proved to be a pain.
One possible concern is that these buffers will probably show up as
memory leaks i.e. with valgrind. Perhaps we should add in an atexit
call to free this memory right after we allocate it?

support) which could cause things like EOF and read errors while reading
/etc/services to always return a TRY_AGAIN. The perl test suite would alloc a
larger buffer and try again until all memory was exhausted. When we get a read
error, or EOF, it means we didn't get what we wanted, and so we should return
an error. Doing so fixes the failing perl 5.8.2 test.

were including libc-lock.h which had a bunch of weak pragmas. Also,
uClibc supplied a number of no-op weak thread functions even though
many weren't needed. This combined result was that sometimes the
functional versions of thread functions in pthread would not override
the weaks in libc.
While fixing this, I also prepended double-underscore to all necessary
weak thread funcs in uClibc, and removed all unused weaks.
I did a test build, but haven't tested this since these changes are
a backport from my working tree. I did test the changes there and
no longer need to explicitly add -lpthread in the perl build for
perl to pass its thread self tests.
