REORG: http: move http_get_path() to http.c
This function is purely HTTP once http_txn is put aside. So the original
one was renamed to http_txn_get_path() and it extracts the relevant offsets
from the txn to pass them to http_get_path(). One benefit of the new version
is that it returns the length at the same time so that allowed to slightly
simplify http_get_path_from_string() which had to look up the end pointer
previously and which is not needed anymore.
