The new function ensures line numbers in loclists are not beyond end of
buffer. The implementation is very inefficient, because it loads all
buffers in memory.
`eslint` and `lessc` checkers need this function.
Error sorting can't be done as a postprocess function called from
SyntasticMake(), since the final values of some relevant fields (f.i.
type) might not be known yet at that point. Solution: move sorting to
getLocListRaw(), after per-checker quiet_messages. New checker methods
getWantSort() / setWantSort() are needed.
Second problem: some checkers return screen columns mixed with byte
indices. Solution: compute screen columns as needed. Sadly, everything
about working with screen columns is fragile.
Optimisation: merge handling of global and per-checker filters.
Feature: allow [] and '' values for quiet_messages filter elements.
Feature: allow overrides for quiet_messages filters.
Feature: buffer-local auto_jump and quiet_messages.
Safety: add magic specifiers to catch regexps.
Cleanup: minor restructuring for the forthcoming foreign checkers
feature.
YCM has now its own navigation functions, so there is no longer any need
to call it from syntastic.
g:syntastic_delayed_redraws is also gone. Syntastic doesn't use popup
menus, and the only purpose of this variable was to provide a workaround
for a problem triggered by YCM.

New options: g:syntastic_quiet_messages, and a per-checker version
of it named g:syntastic_<filetype>_<checker>_quiet_messages.
Option g:syntastic_quiet_warnings is now deprecated.
Option g:syntastic_ignore_files now refers only to files that shouldn't
be checked.
New variables: g:syntastic_debug_file, the name of a file where to write
debugging messages, in addition to adding them to the message history.
The old g:syntastic_debug is now a sum of flags:
* 1 - trace checker calls
* 2 - dump loclists
* 4 - trace notifiers
* 8 - trace autocommands
* 16 - dump syntastic variables (not implemented yet)
