2019-02-11Make tmerc an alias for etmerc. (#1234)Kristian Evers
* Make tmerc an alias for etmerc This switches the algorithm used in tmerc to the Poder/Engsager tmerc algorithm. The original tmerc algorithm of Evenden/Snyder origin can still be accessed by adding the +approx flag when initializing a tmerc projection. The +approx flag can also be used when initializing UTM projections, in which case the Evenden/Snyder algorithm is used as well. If a tmerc projection is instantiated on a spherical earth the Evenden/Snyder algorithm is used as well since the Poder/Engsager algorithm is only defined on the ellipsoid. +proj=etmerc can still be instantiated for backwards compatibility reasons.

2019-02-07Rename proj_crs_list_destroy() to proj_crs_info_list_destroy()Even Rouault
2019-02-07Add proj_get_crs_info_list_from_database()Even Rouault
This method is intended to be used typically by GUI that lists all possible CRS. What is does could be done by previously existing functions, but it is much faster. It typically runs in less than 0.1s (hot run) versus ~0.5s with the method that consists in enumerating all codes and instanciating a PJ object for each of them.

2019-01-08ISO19111: remove PROJ.5 specific format for CRS (refs #1214)Even Rouault
As discussed in https://github.com/OSGeo/proj.4/issues/1214#issuecomment-452084720, the introduction of a new PROJ.5 format to export CRS using pipeline/unitconvert/axisswap as an attempt of improving the PROJ.4 format used by GDAL and other products is likely a dead-end since it is still lossy in many aspects and can cause confusion with coodinate operations. Consequently the PROJ_5 convention will be identical to PROJ_4 for CRS export. Note: on the import side, I've kept the code that could parse unitconvert and axisswap when building a CRS definition from a pipeline. It is there as a hidden feature as it was kind of a tear to remove that code in case it might still be useful...

2018-11-30C API: do not 'cache' PROJ context in PJ_OBJ objectsEven Rouault
We store the PJ_CONTEXT* in the PJ_OBJ objects, but this might cause issues in multi-threaded uses. For example, before this change, let's imagie: - a PJ_OBJ is created in thread A with a PJ_CONTEXT that is specific to this thread A - PJ_OBJ is transfered to another thread that operates on it. It might thus use the PJ_CONTEXT that was TLS(A) - in the meantime thread A does completely different things, but still operate on its PJ_CONTEXT. We might get a concurrent use of the PJ_CONTEXT despite working on different PJ_OBJ Another situation is when using constructor functions that take two PJ_OBJ. Up to now, we arbitrarily selected the context of one of the arguments to attach it to the new object. So better be explicit on which context is used. For reference, in those wrappers of the C++ API, the context is mostly used for two things: - reporting C++ exceptions as PROJ errors with the error handler attached to the PJ_CONTEXT - using the database handle that is associated with the PJ_CONTEXT.
