Update handling of MatTranspose() with MAT_REUSE_MATRIX

Add error checking for the use of the MAT_REUSE_MATRIX flag in MatTranspose()
Add tests to MatTranspose_XXX to error if the nonzero pattern changes
Add support for MAT_REUSE_MATRIX with changing nonzero pattern for MatTranspose_SeqAIJ()
Remove use of updateAt in MatProductNumeric_AtB_SeqAIJ_SeqAIJ() since MatTranspose() automatically
skips unneeded new transpose
Add MatTransposeSymbolic()
Update to SLEPc that supports these changes
