PROJ/src/transformations/helmert.cpp, branch backport-3125-to-9.0

Workaround 'Overlapping read/write of union is undefined behavior' cppcheck warning (but really fixing them would be more involved)

2021-09-04T16:01:11+00:00

Remap ENOMEM from PROJ_ERR_INVALID_OP to PROJ_ERR_OTHER

2020-12-15T16:53:29+00:00

Revise error codes to have a reduced set exposed in the public API.

2020-12-15T00:13:43+00:00

Fixes #2482

And also add proj_context_errno_string()

Revise gie 'expect failure errno XXXX' strings

Remove old pj_ memory (de)allocation functions

2020-11-20T15:40:40+00:00

Gone are pj_malloc, pj_calloc, pj_dalloc and pj_dealloc. Their primary
function as API memory functions in proj_api.h is no longer there and
the other use as a workaround for old errno problems is no longer valid
either.

Replaced with malloc and free across the codebase.

Helmert: fix regression when rotation terms are 0, but scale is not

2020-08-21T06:45:47+00:00

Fixes #2333
Was due to 3dc92ad7014e1cf20a3bc95c8c21a34a371fcb78

Helmert 2D: do not require a useless convention= parameter

2020-07-24T13:22:53+00:00

Remove old geocent.h/.cpp code

2020-04-11T22:11:57+00:00

Last user, apart from transform.cpp, was the SCH projection. Modify it
to use cart instead.

And move content of geocent.h and .cpp into transform.cpp directly, so
that it can be later wiped up easily.

Modify verbosity level of some debug/trace messages

2019-12-25T09:45:20+00:00

- unitconvert, ell_set and helmert were using debug level, which is
  too verbose. Using trace instead
- proj_trans() was using trace to indicate the operation it selects.
  Changing it to debug

helmert: validate scale parameter to avoid later division by zero. Fixes https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=16106
