1. Remove the char2, char4, char8 and char16 types from postgresql
2. Change references of char16 to name in the regression tests.
3. Rename the char16.sql regression test to name.sql.  4. Modify
the regression test scripts and outputs to match up.

Might require new regression.{SYSTEM} files...

Before, char16 was missing last character for output.

Another PGINDENT run that changes variable indenting and case label indenting.  Also static variable indenting.

Fix pgproc names over 15 chars in output.  Add strNcpy() function.  remove some (void) casts that are unnecessary.

Noted in trying to port to AIX.

The comparison routines for text and char data type give incorrect results
if the input data contains characters greater than 127.  As these routines
perform the comparison using signed char variables all character codes
greater than 127 are interpreted as less than 0.  These codes are used to
encode the iso8859 char sets.
The other text-like data types seem to work as expected as they use unsigned
chars in comparisons.
