Pin state reporting of all pins. Flash optimization.

- New pin state realtime reporting feature. Instead of `Lim:000` for
limit state reports, the new feature shows `Pin:000|0|0000`, or
something similar. The `|` delimited fields indicate xyz limits, probe,
and control pin states, where 0 is always not triggered, and 1 is
triggered. Invert masks ARE accounted for.
  Each field may be enabled or disabled via the `$10` status report
setting. The probe and control pin flags are bits 5 and 6, respectively.

- Remove the now deprecated `REPORT_CONTROL_PIN_STATE` option in
config.h

- The old limit pin reports `Lim:000` may be re-enabled by commenting
out `REPORT_ALL_PIN_STATES` in config.h.

- Incremented the version letter (v1.0c) to indicate the change in
reporting style.

- Replaced all bit_true_atomic and bit_false_atomic macros with
function calls. This saved a couple hundred bytes of flash.

+- G38.x was not printing correctly in the $G g-code state reports. Now
+fixed.
+
+- When investigating the above issue, it was noticed that G38.x
+wouldn’t show at all, but instead a G0 would be printed. This was
+unlike the v0.9j master build. It turned out volatile variables do not
+like to be defined inside a C struct. These are undefined on how to be
+handled. Once pulled out, all weird issues went away.
+
+- Also changed two ‘sizeof()’ statements in the mc_probe() and
+probe_state_monitor() functions to be more robust later on.
+
+- Updated the commit logs to individual files for each minor release.
+Forgot to update the generating script to account for this.

+- Potential bug regarding volatile variables inside a struct. It has
+never been a problem in v0.9, but ran into this during v1.0
+development. Just to be safe, the fixes are applied here.
+
+- Updated pre-built firmwares with these two bug fixes.
