ACPICA: Cleanup for all string-to-integer conversions
ACPICA commit e2e72a351201fd58e4694418859ae2c247dafca0
Consolidate multiple versions of strtoul64 to one common version.
limit possible bases to either 10 or 16.
Handles both implicit and explicit conversions.
Added a 2-character ascii-to-hex function for GPEs and buffers.
Adds a new file, utstrtoul64.c
