* UUID support functions.

* This table is used to convert an input UUID ascii string to a 16 byte
* buffer and the reverse. The table maps a UUID buffer index 0-15 to
* the index within the 36-byte UUID string where the associated 2-byte
* hex value can be found.
*
* 36-byte UUID strings are of the form:
* aabbccdd-eeff-gghh-iijj-kkllmmnnoopp
* Where aa-pp are one byte hex numbers, made up of two hex digits
*
* Note: This table is basically the inverse of the string-to-offset table
* found in the ACPI spec in the description of the to_UUID macro.
