msgb: Add msgb_resize_area and msgb_copy
These functions originate from openbsc/src/gprs but are generic
msgb helper functions.
msgb_copy: This function allocates a new msgb, copies the data
buffer of msg, and adjusts the pointers (incl. l1h-l4h)
accordingly.
msgb_resize_area:
This resizes a sub area of the msgb data and adjusts the
pointers (incl. l1h-l4h) accordingly.
