Quincey Koziol 32220914a5 [svn-r7401] Purpose: 
Code cleanup

Description:
    Remove various "fixtype" routines which duplicate (and actually pre-date)
    the functionality in H5Tget_native_type in favor of having the tools call
    H5Tget_native_type().  This provides the same functionality (actually better
    functionality, since the old "fixtype" routines didn't handle alignment of
    compound fields correctly) and reduces the amount of code to maintain.

    Add additional tests to dump out a "complex" compound datatype which
    exercises more code in the library for aligning compound fields correctly.

Platforms tested:
    FreeBSD 4.8 (sleipnir)

* data in hexadecimal format without translating from what appears on
* disk.
*
* raw: If set then print all data as hexadecimal without
* performing any conversion from disk.
*
* fmt_raw: The printf() format for each byte of raw data. The
* default is `%02x'.
*
* fmt_int: The printf() format to use when rendering data which is
* typed `int'. The default is `%d'.
*
* fmt_uint: The printf() format to use when rendering data which is
* typed `unsigned'. The default is `%u'.
*
* fmt_schar: The printf() format to use when rendering data which is
* typed `signed char'. The default is `%d'. This format is
* used ony if the `ascii' field is zero.
*
* fmt_uchar: The printf() format to use when rendering data which is
* typed `unsigned char'. The default is `%u'. This format
* is used only if the `ascii' field is zero.
*
* fmt_short: The printf() format to use when rendering data which is
* typed `short'. The default is `%d'.
*
* fmt_ushort: The printf() format to use when rendering data which is
* typed `unsigned short'. The default is `%u'.
*
* fmt_long: The printf() format to use when rendering data which is
* typed `long'. The default is `%ld'.
*
* fmt_ulong: The printf() format to use when rendering data which is
* typed `unsigned long'. The default is `%lu'.
*
* fmt_llong: The printf() format to use when rendering data which is
* typed `long long'. The default depends on what printf()
* format is available to print this datatype.
*
* fmt_ullong: The printf() format to use when rendering data which is
* typed `unsigned long long'. The default depends on what
* printf() format is available to print this datatype.
*
* fmt_double: The printf() format to use when rendering data which is
* typed `double'. The default is `%g'.
*
* fmt_float: The printf() format to use when rendering data which is
* typed `float'. The default is `%g'.
*
* ascii: If set then print 1-byte integer values as an ASCII
* character (no quotes). If the character is one of the
* standard C escapes then print the escaped version. If
* the character is unprintable then print a 3-digit octal
* escape. If `ascii' is zero then then 1-byte integers are
* printed as numeric values. The default is zero.
*
* str_locale: Determines how strings are printed. If zero then strings
* are printed like in C except. If set to ESCAPE_HTML then
* strings are printed using HTML encoding where each
* character not in the class [a-zA-Z0-9] is substituted
* with `%XX' where `X' is a hexadecimal digit.
*
* str_repeat: If set to non-zero then any character value repeated N
* or more times is printed as 'C'*N
*
* Numeric data is also subject to the formats for individual elements.

*
* 1st: This is the format to print at the beginning of the first
* line of output. The default value is the current value of

* data which is longer than one line of output. The default

*
* 0: No consideration. Each new element is printed
* beginning where the previous element ended.
*
* 1: Print the current element beginning where the

* in the element occupying more than one line and it
* would only occupy one line if it started at the
* beginning of a line, then it is printed at the
* beginning of the next line.

* unless it wouldn't fit.
