cpp conversion: minimal steps to fix compilation errors, not warnings

No longer declare pj_prime_meridians, pj_ellps and pj_units as extern C, but static'ify them

Move struct definitions for proj_list_* functions to proj.h

2018-10-16T19:32:00+00:00

With projects.h not being available to outside users anymore we need to
define PJ_UNITS, PJ_ELLPS, PJ_PRIME_MERIDIANS and PJ_OPERATIONS
elsewhere.

Related pj_get_*_ref() functions have been removed in favour
of their proj_ namespaced counterparts.

char pointers have been changed to const char pointers.

Remove angle brackets for proj headers (#849)

2018-03-11T12:17:07+00:00

* Avoid using angle brackets for PROJ headers.

Switching from #include  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

Declare non-local variables as const where possible

2017-12-17T22:34:40+00:00

Having non-const variables of static lifetime or even global scope is
usually a bad idea. These variables are inherently constants, and this
should be enforced.

This required marking some functions as not modifying input parameters
and marking some pointers as pointers to const.

One advantage is that the compiler usually puts const static variables
in a read-only code segment, so they can't be modified physically.
This can be verified with `nm` (on POSIX systems).

To avoid changes to the public API, functions returning non-const
pointers to data tables were left intact, but the returned data may not
be modified. Internally we prefer using the proj_list_* functions over
the pj_get_*_ref functions, because the former return const pointers.

Remove unused $Id$ keywords.
