XIP execution from ROMFS file systems. Initial check-in is untested
and probably breaks many builds.

* Name: symtab_findbyname
*
* Description:
* Find the symbol in the symbol table with the matching name.
* This version assumes that table is not ordered with respect to symbol
* name and, hence, access time will be linear with respect to nsyms.
*
* Returned Value:
* A reference to the symbol table entry if an entry with the matching
* name is found; NULL is returned if the entry is not found.
