strptime: Fix day-of-week calculation.

The day-of-week calculation used the raw year value without adjusting
for TM_YEAR_BASE, so it was off by one for 300 years out of every 400;
it just happened to be correct for 1901 through 2000. It also used a
loop where a simple addition would have sufficed.

While here, simplify our version of Gauss's algorithm, and document
that we assume the Gregorian calendar.

libc: tests: add testing infrastructure for _FORTIFY_SOURCE

The _FORTIFY_SOURCE tests will be generated by a lua script to avoid a
lot of redundancy in writing these tests. For each function that we're
fortifying, the plan is to test at least the following three scenarios:

- Writing up to one byte before the end of the buffer,
- Writing up to the end of the buffer,
- Writing one byte past the end of the buffer

The buffer is shoved into a struct on the stack to guarantee a stack
layout in which we have a valid byte after the buffer so that level 2
fortification will trip and we can have confidence that it wasn't some
other stack/memory protection instead.

The generated tests are divided roughly into which header we're
attributing them to so that we can parallelize the build -- the full set
is a bit over 9000 lines of C and takes 11s to build on the hardware
that I'm testing on if it's a single monolothic file.

dtrace: Add the 'oformat' libdtrace option

This option can be used to specify a format to use in DTrace output.
The following formats are supported:
- json
- xml
- html
- none (default DTrace output)

This is implemented using libxo and integrated into libdtrace. Client
code only works with the following API:

- dtrace_oformat_setup(dtrace_hdl_t *) -- to be called when output is starting.
- dtrace_oformat_teardown(dtrace_hdl_t *) -- to be called when output is finished
- dtrace_oformat(dtrace_hdl_t *) -- check if oformat is enabled.
- dtrace_set_outfp(FILE *) -- sets the output file for oformat.
- Ensure that oformat is correctly checked in the drop handler and record
processing callbacks.

This commit also adds tests which check if the generated output is
valid (JSON, XML) and extends the dtrace(1) describing the structured output.
