Removed strcpy() call from most common case
Added test for hash index generation

Added test for duplicate field names when returning rows as hashes or objects

Fixed a couple of inconsistencies in param binding
# Previously, empty strings were either rejected (for scaled integers)
# or silently converted to 0 (unscaled integers & floats). Also, in some
# cases, null zvals were converted to empty strings, which were
# consequently rejected as unconvertible values.
# In the new situation, empty strings will be handled as NULLs for
# fields that cannot distinguish between the two (numeric/date/time).
# Additionally, all range and value checking is now carried out by the
# database, so there is a consistent interface for error handling.

Dropped support for ancient Interbase versions (< 6)
# This has no consequences for Firebird, as its initial release was based on IB 6

Fix unregistered bug in zval pointer/array juggling
# Thinko: element of a **zval[] is usually not a *zval[]
# I can't believe this has gone undetected for 4+ years!

Fixed unregistered bug: array count is incorrect when binding array ids
Fixed unregistered bug: empty numeric/datetime param argument is coerced to
a string that cannot be handled by
