Write test cases for the former.

f82bbc1400 Catch up with OpenPAM's latest OATH changes: 
Add an oath_mode(3) function which translates from mode names to numbers.

 Consistently use UINT_MAX, not -1, to indicate an invalid response.

 Change the meaning of the window parameter to always indicate the number
 of codes to check *in addition* to the current code.  Note that for TOTP,
 the window goes in both directions; a window of 1 means to check the
 current code plus the previous and next.

6ed802ddf3 Consistently use #if HAVE_FOO instead of #ifdef HAVE_FOO. The reason is 
that AC_CHECK_DECLS([foo]), unlike AC_CHECK_FUNCS([foo]), will always
define HAVE_FOO, so #ifdef HAVE_FOO will always be true even if it is 0.
This commit finally fixes the [bl]e{32,64}{enc,dec} issue on Linux.

8ef2266a4b r103 was incomplete. It changed the checks in the configure script (and 
accidentally introduced a no-op line), but did not change the checks in
the header, so we ended up always using our own [bl]e{32,64}{enc,dec}.

e4dd25fa79 Use wstring throughout (except internally in struct cpe_name). 
Add a typedef for struct cpe_name and use it throughout.

f7bdd342dc Add our own version of <endian.h> which includes implementations of the 
unaligned encoding / decoding functions which Linux lacks.

1fbf2cf156 It appears that gcc does not accept partial struct initialization. Add 
a CRYB_MPI_ZERO macro that expands to an all-zeroes initializer.

479ffbba4a Remove author and sponsor tags; we'll deal with that some other way. 
Remove $Cryb$ tags as it is likely that the code will move to git.

340b3240cf Consistently use const void * for data and keys, uint8_t * for digests 
and MACs, and uint8_t, uint32_t or uint64_t (as appropriate) for internal
state.  Also remove a few unnecessary casts.

5bb81214cc Instead of storing the key in the hmac_sha1_ctx so we can compute the 
output pad in hmac_sha1_final(), prepare a sha1 context in advance and
discard the key as early as possible.
Inspired by Colin Percival's HMAC-SHA-256 implementation.

efd34d4cc7 In an earlier version of the API, the _init function was responsible 
for allocating the context structure.  This is no longer the case, but
the _init function type was not updated to reflect this.
