* Fixed use of null pointer identified by UBSan
UBSan warned:
runtime error: member access within null pointer of type 'named_dt_t' (aka 'struct named_dt_t')
with these two tests:
H5REPACK-committed_dt_DFF
H5REPACK-committed_dt
Reformulated per @gnuoyd suggestion.
* Fixed undefined float -> unsigned char conversion in HL_test_image
* Removed dead skip_overflow_tests_g global
The global `skip_overflow_tests_g` was being set but never read.
* Don't treat 2d array as 1d array, fixing UBSan complaint in `CPP_testhdf5`
* Committing clang-format changes
* Remove extra ']' in line 730.
