Before that, approximately half of the descriptions had a period at the
end, e.g. 'Cyl.' or 'Sph.' and the other half did not have those periods.
This commit drops all the dots in PROJ_HEAD descriptions.

* Removed remaining traces of the builtin selftest system. Moved all functionality to test/gie

* Updated Appveyor and Travis build scripts

* Another appveyor script update

All projections starting with "a". Replace with stubs returning 10000.

The two PJ_apply_?gridhift.c files have not been touched

In most cases memory deallocation is completely removed from the
code since it can be handled by the default destructor. In a few
special cases a local destructor overrides the default destructor
and makes sure that locally allocated memored is cleaned up correctly.

Move all deallocation from pj_free to pj_default_destructor
Rename pj_latlong.c to fit with the conventional format PJ_latlong.c - freeup was missed here due to wrong naming
Clean up pj_init to avoid double deallocation; Also resolve #576 by adding z_0 and t_0 options in pj_init, while cleaning

Add a prototype for dealloc_params
Added missing errno.h include in pj_ctx.c
Temporarily removing ob_tran from testvarious, to be sure that is where the trouble is
Make PJ_ob_tran.c use proper initialization for the chained projection
proj=ob_tran: make it clear, that we disallow ellipsoidal projections, and, for improved backwards compatibility, turns off default settings, which could inject unwanted ellipsoid definitions
... then also remove the ellipsoid definition from the testvarious test case - which is probably buggy anyway
Work around cs2cs spherical init bug in testvarious; Forbid defs for ob_tran in pj_init

An intermediate file, PJ_etmerc.c, was mistakenly committed in
1b17a573ffb07e9565e0df296e2a3a21bce8e971

P->pfree and P->descr were being identically reinitialized in a few of
the first files converted - and in the last: proj_etmerc.c

Continuing alphabetically, with a few detours due to the occasional case
of more than one projection in one source file.
