add support imx6 I2C Controller
As is evidenced by several of our 32-bit MIPS ports, it's wrong to
print vsize_t with PRIx64 -- instead use our own PRIxVSIZE macro.
Canonical Minix check as pointed out by Marc
Do the previous correctly...
No functional change.
- 0 -> NULL
- Don't use cast.
- Style fix.
- Fix typos in comment.
In the exp2_values test case, provide separate expected return values
for the float case, reflecting the actual exp2f() argument value after
rounding to float precision.  Fixes PR lib/49256.  Thanks to Makoto
Kamada and Tetsuya Isaki for the analysis.
sleep for 0.05 seconds instead of 2 seconds when checking if the pids
are still alive for a much faster exit.
Add local parsecheck() function and use it for several tests.

Instead of just checking that parsedate(3) does not return an error,
also pass the result through localtime_r(3) or gmtime_r(3) and check the
year/month/day/hour/minute/second fields in the resulting struct tm.
Add comments for some non-obvious cases.
Also add a test with year=70, which is documented to be treated as 1970.
fix some c&p bugs.

don't define functions we define in our own headers
Some years don't need the "maybe add 1900 or 2000" adjustment
that was designed for handling two-digit abbreviated years.
For example, "1/2/70" still refers to the year 1970, as before,
but "70-01-02" now refers to the year 70.

* Add a new yyHaveFullYear member to struct dateinfo, to record whether
  or not the year needs to be adjusted.
* Code that parses years sets yyHaveFullYear=1 if they know that the
  year should not be adjusted (as is the case for ISO 8601 dates), or if
  they perform their own adjustment (as is the case for CVS timestamps).
* Move the year adjustment code into a new function, AdjustYear,
  instead of inline in Convert().
* Make Convert() assume the year doesn't need to be adjusted,
  and make Convert's callers first call AdjustYear() if appropriate.
