2017-07-07obs_api revision and improvements: new namespace etc. (#530)Thomas Knudsen
* obs_api revision and improvements: new namespace etc. * Minor corrections: use unused functions, add missing prototype, added fwd/invcoord to PJ * Minor correction: MSVC barfs on va_arg type specification. Trying once more with added parens * Reverting paren correction, which appears to be a non-solution * Significant improvements to the OBS_API, plus a number of corrections, mostly in test code, to reflect API changes * Added two missing prototypes * Adding the proj_transform function and some related checks * Improvements to proj_transform etc. based on suggestions from Even Rouault * Reducing the libc include footprint of proj.h - again based on suggestions from Even Rouault * A few minor corrections * Eliminate a MSVC warning about non-initialized usage. Not an actual issue, as another check has locked the path, but at least this should calm down MSVC * Improved support for the errno reset/restore paradigm * Introduced the internal header proj_internal.h; Moved most non-API stuff from pj_obs_api.c to pj_internal.c * Adding proj_internal.h to HEADERS_LIBPROJ to solve build problems * Correcting a few pj...proj blunders in PJ_pipeline.c * Correcting a few additional blunders in PJ_pipeline.c * Changed angle-brackets to quotation marks in includes of proj_internal.h * Some minor build system repairs * Some PJ_CONTEXT usage simplifications following suggestions by Kristian Evers @kbevers * Added version numbering to proj.h - Fixes #529 * remove proj_errno_restore macro, provide function implementation * Add proj_get_definition. Fixes #538 * Added library specific deallocator proj_buffer_free, eliminating a potential cross heap issues on Windows. Thx to Even Rouault for spotting this * Got rid of a meaningless cast in proj_buffer_free * Added some missing functions to proj.def (again spotted by @rouault); removed some not-yet-implemented material from proj.h * Renamed proj_get_definition/proj_buffer_free to proj_definition_create/proj_definition_destroy, for symmetry and clarity * Renaming the definition handlers to proj_definition_retrieve / proj_free * Renaming proj_free to proj_release

2017-07-05Let pj_init() expand more than one +init argument.Kristian Evers
With the introduction of transformation pipelines it is now a valid use case to have more than one +init argument in a proj string. This commit makes sure that all +init's are expanded. Added test case to PJ_pipeline.c for use of multiple +init's in a proj-string. Fixes #479.

2017-05-24Remove confusing macros.Elliott Sales de Andrade
The upper-case macro `VAR` casts the lower-case variable `var` to an expected type, but that usage obfuscates the variables to the casual reader. This is especially prevalent in the allocation function in which `var` is the correct type already, so both `var` and `VAR` are valid *and* in use. In any case, for those functions that don't obtain `var` in the correct type from their parameters, it's much simpler to just case once at the beginning.
