Match one-line MEOS-C definitions when attaching @csqlfn

[estebanzimanyi]

attach_sqlfn_map links each MEOS-C function to its SQL name by finding the function definition that follows a @csqlfn doxygen block. _FNDEF matched that definition only when the return type sat on its own line (bool\nname(). A one-line definition — bool tpcbox_eq(const TPCBox *box1, ...), the pointcloud predicate style — was not matched, so the tag attached to the next matchable definition instead. Several wrappers then collapsed onto one MEOS function, and the skipped functions were left with no SQL name.

The regex now also accepts an optional same-line return-type prefix (word/space/*) before the name, so both layouts resolve.

Regenerating the catalog against master restores the SQL name of ten functions that were previously dropped from every binding — the tpcbox_eq, tpcbox_ne, tpcbox_lt, tpcbox_le, tpcbox_gt, tpcbox_ge comparison operators, the tpcbox_hasx/tpcbox_hasz/tpcbox_hast accessors, and pcpatch_get_pcid — and changes nothing else (thirteen catalog entries move, all corrections; the test suite is green: 147 passed, 14 skipped).
