Fixes consist in:
- no use of comma operator for multi statement purpose
- avoid confusing comma in for loops first and third clauses
- avoid implicit long to int casts by storing to long, or explicit bound checking before cast

Code updated to use isnan() instead of pj_is_nan().

|
|
Extend HAVE_C99_MATH checks in CMakeLists.txt and configure.ac to
include test for C99 function isnan.

* Avoid using angle brackets for PROJ headers.
Switching from #include <proj.h> to #include "proj.h",
and correspondingly for projects.h and proj_api.h,
reduces the risk of accidentally picking up a system
installed older version of the header while building
a new version of PROJ.
* Also handle geodesic.h

* Shrink PJ_XXX_INFO structs, but keep same syntax.
A number of the fixed length strings in the INFO structs are simply
reflections of material that already exists as static strings at a
number of places in the library (or in the case of PJ_INFO, really
*should* exist, and now is implemented).
This PR replaces these cases of constant length strings with const
char pointers. The usage syntax is unchanged, and so is the nice
property of having the return value allocated on the stack, and
hence not requiring explicit memory management by the caller.
proj_info now only does setup once - and the searchpath entry of
PJ_INFO is not arbitrarily truncated at 512 bytes. Repeated calls
simply returns a copy of already prepared material.
The id, description and definition entries of PJ_PROJ_INFO are now
also guaranteed to hold the entire text of the corresponding static
string, by being represented by a const char pointer to that actual
static string.
PJ_GRID_INFO and PJ_INIT_INFO (i.e. the two smallest INFO structs)
are unchanged.
* Eliminate pj_strlcpy - not needed anymore: Remining calls could
safely be replaced by strncpy.
* Extend PROJ_INFO with paths from pj_set_searchpath.
NOTE: Need to call pj_set_searchpath before first call to proj_info
Huge thanks to Kristian Evers and Even Rouault for comments, debugging and advice.

With the introduction of the "inverted" flag on PJ objects
you can no longer rely on checking that the inv, inv3d and inv4d
functions are available on said PJ object. The function is used
internally a few places and otherwise exposed in proj_api.h to
ensure that users of the old programming interface can safely
check if an operation has an inverse.

arbitrary dimensionality in test code
* Call trans func of same dimensionality as input in gie
* Refactor prep/fin code for pj_fwd/pj_inv 2D,3D,4D
* Remove prime meridian handling from pj_transform (now handled in pj_fwd_prepare/pj_inv_finalize)
* Introduce prep/fin skips, mostly in support of axisswap and pipeline drivers
* Refactor fwd/inv subsystem
* pj_transform: Let pj_fwd/inv handle scaling
* Let pj_fwd/inv3d fall back to 2D eventually

* Enable selective debug printout through negative PROJ_DEBUG values

PJ_OBS eliminated, API adjusted to reflect that we now have only one 4D data type.
2 new API functions added to determine output types of a PJ.
|
|
* Remove a number of debugging calls and memory management from the inner loop of the pipeline drivers
* An attempt at handling inverted steps in a more straightforward way
|
|
* Remove PJ_OBS from the API surface, rename pj_obs_api.c to pj_4D_api.c
* Repair proj.def

* Adding info functions to proj.h API.
Four new functions are added with this commit: proj_info(), proj_pj_info(),
proj_grid_info() and proj_init_info(). Additionally four new data types are
added: PJ_INFO, PJ_PROJ_INFO, PJ_GRID_INFO and PJ_INIT_INFO. The functions
return the corresponding data types.
These functions allows users of the PROJ.4 library to get information about
various PROJ.4 entities and the library itself. The new data types are structs
that contain specific information about either the library instance, a PJ
instance, a grid or an init file. Together the four new functions cover a big
part of the functionality in the semi-public projects.h API and should hopefully
make it easier for user to migrate their code to the proj.h API in the future.
Besides covering already existing functionality in the old API, this commit
introduces the ability to add metadata to init-files. This is primarily added
to give users a way of knowing which version of the EPSG database they are
using, but it also comes in handy for other init-files. The init-file metadata
is added directly to the init-file as a special "projection" called "metadata".
The info projection of the epsg init-file is thus described as:
<metadata> +version=9.0.0 +origin=EPSG +lastupdate=2017-01-10
The proj_init_info() function uses the internal pj_param() to read the
metadata. As a consequence, "metadata" will not be available as a the name of
a projection in the future. This is a reasonable price to pay considering the
ease of the implementation of adding metadata to init-files this way, and of
course that "metadata" is a very unlikely name for a projection in any case.
A metadata tag has been added to all init-files in the nad-directory. For most
only a subset of the possible parameters has been added.
* Replaced calls to sprintf and strncpy with safer options. Added pj_strlcpy for internal use.
* Fail gracefully when getting non-initialized PJ in proj_pj_info()
* Change length of filename member in PJ_INIT_INFO and PJ_GRID_INFO to 260 (MAX_PATH)

* 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
