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.
* Differentiate character lengths from byte lengths (see #112)
* Use GNU-style indexed initializers for clarity
* Remove needs_quotes since it's not used anywhere
* MDBOPTS=no_memo is not used anywhere; mark deprecated and print a
warning if enabled
* Mark MDBOPTS=use_index as experimental in the man pages
* MDBOPTS need to be colon separated
* Document new long forms of mdb-queries options
GLib will automatically convert command line options to UTF-8 provided that setlocale(LC_TYPE, "") is called first, and the argument type is STRING (but not FILENAME). Update the CLI tools to take advantage of this behavior, and likewise implement it in fakeglib.
GLib does not automatically convert non-option arguments (i.e. everything remaining in argv after option processing), so manually call g_locale_to_utf8 on these arguments when they represent table names. This should fix the CLI tools when processing non-ASCII table names in non-UTF-8 locales. Also update fakeglib to implement a fast and loose version of g_locale_to_utf8, and factor out some of the code page => iconv name logic in iconv.c so it can be used in our fake g_locale_to_utf8. This adds a new symbol mdb_iconv_name_from_code_page that is not advertised in the main header file. I did not want to include mdbtools.h from fakeglib.c, but maybe that's not important.
Other programs (e.g. gmdb2) use mdb_print_col, so restore the old enum
names and values. MDB_EXPORT_ESCAPE_INVISIBLE can be OR'ed into the
last argument to enable C-style escaping of text fields.
Print a warning if use_index is turned on but libmswstr is not found. I
suppose we could enable indexes only on JET3 databases, but I am not at
all confident in the JET3 index logic, as it seems to break on non-ASCII
input. So I'd rather just print this warning and require some
hoop-jumping.
