crypto: testmgr - eliminate redundant decryption test vectors

Currently testmgr has separate encryption and decryption test vectors
for symmetric ciphers.  That's massively redundant, since with few
exceptions (mostly mistakes, apparently), all decryption tests are
identical to the encryption tests, just with the input/result flipped.

Therefore, eliminate the redundancy by removing the decryption test
vectors and updating testmgr to test both encryption and decryption
using what used to be the encryption test vectors.  Naming is adjusted
accordingly: each cipher_testvec now has a 'ptext' (plaintext), 'ctext'
(ciphertext), and 'len' instead of an 'input', 'result', 'ilen', and
'rlen'.  Note that it was always the case that 'ilen == rlen'.

AES keywrap ("kw(aes)") is special because its IV is generated by the
encryption.  Previously this was handled by specifying 'iv_out' for
encryption and 'iv' for decryption.  To make it work cleanly with only
one set of test vectors, put the IV in 'iv', remove 'iv_out', and add a
boolean that indicates that the IV is generated by the encryption.

In total, this removes over 10000 lines from testmgr.h, with no
reduction in test coverage since prior patches already copied the few
unique decryption test vectors into the encryption test vectors.

This covers all algorithms that used 'struct cipher_testvec', e.g. any
block cipher in the ECB, CBC, CTR, XTS, LRW, CTS-CBC, PCBC, OFB, or
keywrap modes, and Salsa20 and ChaCha20.  No change is made to AEAD
tests, though we probably can eliminate a similar redundancy there too.

The testmgr.h portion of this patch was automatically generated using
the following awk script, with some slight manual fixups on top (updated
'struct cipher_testvec' definition, updated a few comments, and fixed up
the AES keywrap test vectors):

    BEGIN { OTHER = 0; ENCVEC = 1; DECVEC = 2; DECVEC_TAIL = 3; mode = OTHER }

    /^static const struct cipher_testvec.*_enc_/ { sub("_enc", ""); mode = ENCVEC }
    /^static const struct cipher_testvec.*_dec_/ { mode = DECVEC }
    mode == ENCVEC && !/\.ilen[[:space:]]*=/ {
    	sub(/\.input[[:space:]]*=$/,    ".ptext =")
    	sub(/\.input[[:space:]]*=/,     ".ptext\t=")
    	sub(/\.result[[:space:]]*=$/,   ".ctext =")
    	sub(/\.result[[:space:]]*=/,    ".ctext\t=")
    	sub(/\.rlen[[:space:]]*=/,      ".len\t=")
    	print
    }
    mode == DECVEC_TAIL && /[^[:space:]]/ { mode = OTHER }
    mode == OTHER                         { print }
    mode == ENCVEC && /^};/               { mode = OTHER }
    mode == DECVEC && /^};/               { mode = DECVEC_TAIL }

Note that git's default diff algorithm gets confused by the testmgr.h
portion of this patch, and reports too many lines added and removed.
It's better viewed with 'git diff --minimal' (or 'git show --minimal'),
which reports "2 files changed, 919 insertions(+), 11723 deletions(-)".
