This changeset implements Lane Anticipation on roundabouts, delimited
by enter / leave step pairs. It does not handle lane anticipation
within a roundabout.
Lane anticipation happens on the granularity of a valid roundbaout:
We discard partial roundabout (enter without exit or exit without
enter) or data issues (no roundabout, exit before enter).

* formats 'hh:mm:ss' and ISO 8601 are merged into one grammar.
* iso_8601_grammar is changed to static const.
* iso_8601_grammar supports formats P[n]DT[n]H[n]M[n]S, P[n]W,
and part of alternative PTHHMMSS and extended PTHH:MM:SS formats.
Changes:
* LeafNode is aligned to LEAF_PAGE_SIZE.
Alignment brings 24 bytes memory overhead for 4096, but reduces
cache misses rate.
* Unused m_element_count from leaf nodes file.
The size is computed as m_leaves_region.size() / LEAF_PAGE_SIZE.
* Added try/catch for mmap exceptions messages.
candidate_cache is removed because of failing test

first bad commit: [9692be6f50] Add cache for CandidateSegments to reduce heap worke even more
Now SegmentIndex contains leaf index, object index and fixed_projected_coordinate
In windows native strings in Lua incorrectly
interpreted because native separators must be escaped.
Use of generic strings prevent use of backslashes and
"Generic paths are portable and independent of the operating system.".
