Wildcards for Header Removal

The device supports the use of the "*" wildcard character to remove headers. The "*" character may only appear at the end of a string. For example, "X-*" is a valid wildcard request, but "X-*ID" is not.

Below are examples of using the wildcard:

header.p-*: Removes all headers that have the prefix "p-".
header.x-vendor*: Removes all headers that start with "x-vendor".

The wildcard doesn't remove the following headers: Request-Uri, Via, From, To, Callid, Cseq, and Contact.
