TurboJPEG: Thread-safe error message retrieval

Browse Source 
Introduce a new C API function (tjGetErrorStr2()) that can be used to
retrieve compression/decompression/transform error messages in a
thread-safe (i.e. instance-specific) manner.  Retrieving error messages
from global functions is still thread-unsafe.

Addresses a concern expressed in #151.
