 * Buffer types:
 *
 * Many of the routines in this module require the user to supply a
 * buffer into which the desired strings may be written. These are
 * all arrays of characters, and might be defined as simple arrays
 * of char. The problem with that approach is that when such an array
 * is passed to a function, the C language considers it to have the
 * type (char *), without any regard to its length. Not all of our
 * buffers have the same length, and we want to ensure that the compiler
 * will refuse to compile code that passes the wrong type of buffer to
 * a given routine. The solution is to define the buffers as unions
 * that contain the needed array, and then to pass the given union
 * by address. The compiler will catch attempts to pass the wrong type
 * of pointer, and the size of a structure/union is implicit in its type.
 *
 * A nice side effect of this approach is that we can use a union with
 * multiple buffers to handle the cases where a given routine needs
 * more than one type of buffer. The end result is a single buffer large
 * enough to handle any of the subcases, but no larger.
 */

/*
 * Size of buffer used by conv_invalid_val():
 *
 * Various values that can't be matched to a symbolic definition are converted
 * to a numeric string.
 *
 * The buffer size reflects the maximum number of digits needed to
 * display an integer as text, plus a trailing null, and with room for
 * a leading "0x" if hexidecimal display is selected.
 *
 * The 32-bit version of this requires 12 characters, and the 64-bit version
 * needs 22. By using the larger value for both, we can have a single
 * definition, which is necessary for code that is ELFCLASS independent. A
 * nice side benefit is that it lets us dispense with a large number of 32/64
 * buffer size definitions that build off CONV_INV_BUFSIZE, and the macros
 * that would then be needed.

 * Most conversion routines are able to provide strings in one of

 *
 *   DEFAULT
 *	The default string style used by a given conversion routine is
 *	an independent choice made by that routine. Different routines
 *	make different choices, based largely on historical usage and
 *	the perceived common case. It may be an alias for one of the
 *	specific styles listed below, or it may be unique.
 *
 *   DUMP
 *	Style of strings used by dump(1).
 *
 *   FILE
 *	Style of strings used by file(1).
 *
 *   CRLE
 *	Style of strings used by crle(1).
 *
 *   CF
 *	Canonical Form: The string is exactly the same as the name
 *	of the #define macro that defines it in the public header files.
 *	(e.g. STB_LOCAL, not LOCL, LOCAL, LOC, or any other variation).
 *
 *   CFNP
 *	No Prefix Canonical Form: The same strings supplied by CF,
 *	but without their standard prefix. (e.g. LOCAL, instead of STT_LOCAL).
 *
 *   NF
 *	Natural Form: The form of the strings that might typically be entered
 *	via a keyboard by an interactive user. These are usually the strings
 *	from CFNP, converted to lowercase, although in some cases they may
 *	take some other "natural" form. In command completion applications,
 *	lowercase strings appear less formal, and are easier on the eye.
 *
 * Every routine is required to have a default style. The others are optional,
 * and may not be provided if not needed. If a given conversion routine does
 * not support alternative strings for a given CONV_FMT_ALT type, it silently
 * ignores the request and supplies the default set. This means that a utility
 * like dump(1) is free to specify a style like DUMP to every conversion
 * routine. It will receive its special strings if there are any, and

 *	values. Entries with a 0 are quietly ignored.
 *
 *    conv_ds_vd_t (ds_type == CONV_DS_VD)
 *	This structure employs a NULL terminated array of Val_desc structs.
 *	Each Val_desc supplies a mapping from a value in the range
 *	(ds_baseval <= value <= ds_topval). The values described need not
 *	be consecutive, and can be sparse. ds_baseval does not need to
 *	correspond to the first item, and ds_topval need not correspond to
 *	the final item.
 *
 *    conv_ds_vd2_t (ds_type == CONV_DS_VD2)
 *	This structure employs a NULL terminated array of Val_desc2 structs,

 *	as part of the value/string mapping. It is otherwise the same thing
