a44a8ed8ae Postgres-style ILIKE operator (with Unicode support) (#244) 
Access's `LIKE` is actually case-insensitive, but to prevent breaking existing
programs that rely on mdbtools' case-sensitive behavior, introduce a new
`ILIKE` operator to perform a case-insensitive match. Use GLib's `g_utf8_casefold`
to make the comparison UTF-8 aware. A "poor man's" version is implemented
in fakeglib, which relies on `towlower`, and won't work with multi-grapheme
case transformations (e.g. German Eszett).

Fixes #233

246f854b99 Add backticks around table names in mdb-query output (#307) 
* Add [brackets] around mdb-query table names

* Allow column and table names to be in brackets

Column and table names can have whitespace in them.  The traditional way
to indicate that is with bracket characters, like so:
```sql
SELECT [column name] FROM [table name]
```

This change updates the parser to allow bracket format -- similar to
double-quoted format -- in all NAME contexts, i.e., column names, table
names, and database names.

3e11f6dc26 Set _XOPEN_SOURCE to 600. Fixes #301 
Some platforms including RHEL need _XOPEN_SOURCE to be defined as a
particular value. 600 seems to be a popular choice.

615b625d79 Let LC_COLLATE influence string-comparison operations 
By default this will be set to the C locale, but set it to the user's
locale when string comparisons are performed from mdb-sql. Note that
this can be overridden with the LC_COLLATE environment variable.

We could infer the collation locale from the file itself, but this will
likely require a big ball of glue between the Windows locales and Unix
ones.

crap in the source code.

I've left one reference in backend.c to prevent a merge conflict but
this can be removed later.
