Fix buffer over-read in percent_decode().
...
When decoding a trigram, percent_decode() would correctly increment the input pointer by an extra two characters (three total) but would not decrement the input length by the same amount. This would result in a buffer over-read when decoding unterminated strings.

Improve and document percent-encoding API.
...
- Ensure that the output is always NUL-terminated.
- Always include the terminating NUL in the returned length.
- Allow out == NULL, allowing the caller to check how much space is required before allocating.
- Add man page.

Fix t_malloc_snapshot(): stash the difference between nalloc and nfree,
...
not the numbers themselves.
In t_malloc_printstats(), show information about mapped allocations.
In t_malloc_leaked(), check for leaked mapped allocations. Note that
they would show up anyway since the metadata are allocated from the
bucket allocator, but this makes them more visible.

Add t_malloc_snapshot() which writes a snapshot of the allocator state to
...
a caller-provided buffer. Use it to warn about leaks in each individual
test case. Note that we can't fail a test case for leaking, because
individual test cases in a unit may modify shared state which is cleaned
up at the end of the series.

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.
