Alexander Peshkov 6198bc8ee1 High precision datatype support - Numeric(34,x) (#108)
* Raise underflow when close to 0 decfloat value casted to double
* High precision NUMERIC datatype based on DECFLOAT
* Fixed bulk insert mode in isql for decfloat values
* Enforce correct decQuad format after arithmetic operations
* Minimum docs for high precision NUMERIC/DECIMAL

* Some fixes of code suggested by Adriano:
- Use "const" keyword for Decimal128 constants declared internally
- Remove unneeded buffer initialization
- Remove unused function makeDecimalFixed()
- Follow firebird naming conventions to make code better readable and avoid possible conflicts with various .h files
- Added forgotten scale for DecimalFixed
