fstrim applet is a port from util-linux.
"Trimming" your NAND/eMMC storage will restore the write performance
back to normal after having slow down issues on sequential write and
random write due to usage over time.
Good reading on subject:

Commit b8b72f02 removed all padding from DHCP packets
to fix operation with buggy servers which can't handle
maximum sized packets. But it introduced a regression
with buggy routers which drop DHCP packets smaller
than 300 bytes (i.e. 342 byte ethernet packets).
Add back some padding to work around.

md5sum b29ce23312e14eb15a143377d4a38473, was failing to unpack.
It so happened that this file has a run which exactly fills
the 90k buffer. The check was "size >= bufsize", apparently
it has to be ">".

While at it, move applet/config/kbuild bits into wall.c.
(This way, it's more visible that applet is suid'ed).

If our pkg-config queries pass back a flag like -pthread, the trylink
script will expand that to -l-pthread. So change trylink to only add
the -l prefix to a value that doesn't have a - prefix already.

Fron bug report:
If a CGI or proxied connection is rudely aborted (SIG_{KILL,BUS,SEGV})
then httpd will spin madly the poll loop in:
networking/httpd.c:1080
cgi_io_loop_and_exit()
Upon investigation I found that pfd[0].revents == 0x0018 (POLLHUP|POLLERR),
which leads to empty read, but the pfd[0].fd (STDIN_FILENO) is left open,
and in the FD list given to poll() which immediately returns to once
again inform the loop of (POLLHUP|POLLERR) condition of pfd[0].fd.
This continues until pfd[FROM_CGI].revents != 0

ar fields are fixed length text strings (padded with spaces). Ensure
bb_strtou doesn't read past the field in case the full width is used.
The fields are only read once, so the simplest/smallest solution to me
seems to be to just pass the length to read_num() and then zero terminate
the string before passing it to bb_strtou. This does mean that the fields
MUST be read in reverse order, so some minor reshuffling was needed.
