/*
* Determine if string 'value' matches 'nvp' value. The 'value' string is
* converted, depending on the type of 'nvp', prior to match. For numeric
* types, a radix independent sscanf conversion of 'value' is used. If 'nvp'
* is an array type, 'ai' is the index into the array against which we are
* checking for match. If nvp is of DATA_TYPE_STRING*, the caller can pass
* in a regex_t compilation of value in 'value_regex' to trigger regular
* expression string match instead of simple strcmp().
*
* Return 1 on match, 0 on no-match, and -1 on error. If the error is
* related to value syntax error and 'ep' is non-NULL, *ep will point into
* the 'value' string at the location where the error exists.
*
* NOTE: It may be possible to move the non-regex_t version of this into
* common code used by library/kernel/boot.
