0ef64bdb40 *: make GNU licensing statement forms more regular
This change retains "or later" state! No licensing _changes_ here,
only form is adjusted (article, space between "GPL" and "v2" and so on).

6ca409e0e4 trylink: produce even more info about final link stage
trylink: explain how to modify link and drastically decrease amount
  of padding (unfortunately, needs hand editing ATM).
*: add ALIGN1 / ALIGN2 to global strings and arrays of bytes and shorts

bba7f08d27 Add SWAP_LE?? and SWAP_BE?? macros, and make things use them. Converts values
to/from little endian or big endian, which is a NOP if that's what the current
platform already is.

34b5319d86 Make md5 calculation always go through an the buffer so that A) we don't
handle packets out of sequence if some data goes through the buffer and
some doesn't, B) it works on systems that can't handle aligned access,
C) we just have one code path to worry about.

While we're at it, sizeof() and RESERVE_CONFIG_BUFFER() really don't combine
well, which is why md5sum has been reading and processing data 4 bytes at a
time.  I suspect that the existence of CONFIG_MD5_SIZE_VS_SPEED to do loop
unrolling and such in the algorithm was an attempt to work around that bug.

421d9e5941 - move buffer allocation schemes to libbb.h
- include the correct headers: applets need busybox.h while lib* need libbb.h

5cf7c2df66 Patch from Devin Bayer to split up hash_fd.c into md5.c and sha1.c. (I tweaked
md5_sha1_sum.c to convert some #ifdef CONFIG to if(ENABLE).)
