Fix performance regression in refactored syntax cache setup.
More doc improvements.
* syntax.h (enum syntax_source):
New. Specify whether syntax is from property or buffer.
(struct syntax_cache):
Use enum syntax_source source, instead of no_syntax_table_prop
and use_code.
Improve comments.
(SOURCE_IS_TABLE):
New predicate.
(SYNTAX_CODE_FROM_CACHE):
Use it instead of use_code, and adjust logic.
* syntax.c (syntax_cache_table_was_changed):
Check cache->source (cache->no_syntax_table_prop is gone).
(reset_syntax_cache_range):
All information about OBJECT and BUFFER is in CACHE already.
Also reset markers in OBJECT if it is a buffer.
Rename INFINITE to VALID_EVERYWHERE.
(init_syntax_cache):
Initialize source (cache->no_syntax_table_prop is gone).
Maybe initialize start and end to null markers.
Initialize cache range with reset_syntax_cache_range.
(update_syntax_cache):
Use source instead of no_syntax_table_prop and use_code.
(setup_syntax_cache):
Add header comment. Improve other comments.
Make calls to reset_syntax_cache_range and init_syntax_cache match
their prototypes.
(init_buffer_syntax_cache):
Use init_syntax_cache to do the work.
(signal_syntax_cache_extent_changed):
Make call to reset_syntax_cache_range match its prototype.
Improve local variable naming.
