ENH: avoid expensive clears in fenv functions

Clearing is 50-100 times more expensive than checking on x86, so check if there
is anything needs to be cleared first. This speeds up scalar operations
by 10%-20%.
Based on Arink Verma code in #3739.

Implement the functions as new C-API functions npy_get_floatstatus and
npy_clear_floatstatus in npy_math.

BUG: Support ndim=0 when constructing arrays from buffer

Previously the buffer was interpreted as 1-dimensional when
no shape was provided, even when ndim was 0.

Sequence assignment doesn't raise exception on shape mismatch
BUG: Fix chunked reading of strings longer than BUFFERSIZE

This fix correctly calculates the number of BUFFER_SIZE chunks to read.
This fix takes into account dtype sizes that could be larger
than the BUFFER_SIZE, like a long string.
