d6f101daef syntax: sql: colorize keywords regardless of case, and tweak the colors
Make types a bluish green, for more contrast with strings, so that the
latter can be made greener, for more contrast with the yellow keywords.
Make the main keywords bluer and less bright, and unbold and soften the
yellow ones.  Soften the comments too.

Reference for case-insensitivity:

350cdd9827 syntax: sql: colorize strings differently than types
Also, colorize comments more readably (on a dark background), and
schemas less yelling, and languages more distinct from keywords.

And add a few more keywords, like IS and NULL.

5dc48d54f2 syntax: sql: add more missing keywords, like INNER and OUTER JOIN
Also, fold two other regexes together, for conciseness.

41975265bf syntax: sql: add some missing keywords, like ALL and ANY and OR
Also, combine some keywords that can only occur together.
And drop a few that are probably rare, like LARGE OBJECT.

Reference:

And use a more readable color -- blue is too dark on a black base.

248ebf9117 syntax: sql: colorize only single-quoted things as strings
SQL does not know double-quoted strings.  Double quotes can be used
around identifiers, to prevent them being interpreted as keywords.

56aacb3e32 syntax: sql: colorize as flow control only keywords that clearly are such
Drop things that were recolored afterward (like CLASS and DEFAULT).
Also, move these coloring rules to after the other keywords so that
things like "END IF" will stay colored as a whole.

f2c9aed16c syntax: sql: remove alien stuff -- it was copied mostly from ruby syntax
Regular expressions in SQL are not written between // or %r{},
strings are not written between <> or %Q{} or anything similar,
and comments do not start with # -- and officially not with //
either, but some dialects seem to allow it.

This fixes https://savannah.gnu.org/bugs/?61381.

Bug existed since version 2.4.2, since the SQL syntax was included.
