Subject: [PATCH] lavf/rtpdec_g726: Map mime type G726 to g726le.
Add new mime types AAL2-G726 for g726 as suggested in rfc 3551.
This patch will break applications that incorrectly use big-endian
G.726 with mime type G726 but we know of at least one device (DVTel
camera) that correctly implements the rfc, so do the same.
Fixes ticket #5890.
