  r.geomorphon: Refined resolution warning condition, code cleanups (#1093)

Refine a warning condition for resolution:

In one configuration r.geomorphon would always warn about the resolution
mismatch even after g.region had aligned the region. Apparently, the
four values in the comparison were equal up to 16 decimal places. The
difference seems to come from different calculations producing different
cumulative rounding errors. Add a small (less than 1mm in LatLong
projection) margin to squelch the warning when the difference is
negligible.

Make global_ternary_codes[] static:

The only code that uses the array is in geom.c, so make the array static
and export an initialization function to call from main(). Use a macro
instead of hard-coded constants and get the array size right.

Lose an unused function argument: extends() never used pattern_size, so get rid of it.

Fix W3C HTML validator issues for doc: required attribute "ALT" not specified,
document type does not allow element "H2" here, end tag for "DL" omitted.
