Details: - Split existing typed APIs into two subsets of interfaces: one for use with expert parameters, such as the cntx_t*, and one without. This separation was already in place for the object APIs, and after this commit the typed and object APIs will have similar expert and non- expert APIs. The expert functions will be suffixed with "_ex" just as is the case for expert interfaces in the object APIs. - Updated internal invocations of typed APIs (functions such as bli_?setm() and bli_?scalv()) throughout BLIS to reflect use of the new explictly expert APIs. - Updated example code in examples/tapi to reflect the existence (and usage) of non-expert APIs. - Bumped the major soname version number in 'so_version'. While code compiled against a previous version/commit will likely still work (since the old typed function symbol names still exist in the new API, just with one less function argument) the semantics of the function have changed if the cntx_t* parameter the application passes in is non-NULL. For example, calling bli_daxpyv() with a non-NULL context does not behave the same way now as it did before; before, the context would be used in the computation, and now the context would be ignored since the interace for that function no longer expects a context argument.
