* 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

* Removed remaining traces of the builtin selftest system. Moved all functionality to test/gie
* Updated Appveyor and Travis build scripts
* Another appveyor script update

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

Expanded *_ERROR* macros with calls to proj_errno_set() and proper
returns when necessary. Defined a bunch of new PJD_ERR_ constants in
projects.h that corresponds to the error numbers in pj_strerrno.c. A few
unknown error numbers were replaced by existing ones in pj_strerrno.c.

Introducing the Horner polynomial evaluator also introduces the need for
very long +init:tag arguments (a n'th order 2D polynomium has
(n+1)(n+2)/2 coefficients, and n is typically in the range 5-10, i.e. up
to around 60 coefficients for each polynomium, and there are 4 polynomia
in a complete back/forward transformation set).
Hence, in this commit, along with the first part of the Horner code, the
code for reading +init files has been modified in a (for all practical
purposes) backwards compatible way, by making it possible to introduce
line continuations by escaping line breaks, i.e. preceding them with a
backslash.
An escaped line break works (as it would in TeX), by skipping all
following whitespace, including interspersed #-comments. This simple
extension makes it possible to create very long initialization elements
without losing track of the structure (cf. s45b.pol and pj_init_test.c
in the examples-directory for a demo).
The s45b.pol file was created by hand-editing the output of the software
doing the original constrained adjustment for the polynomial
coefficients. The simple adding of the “skip following whitespace and
comments” feature has made it possible to retain almost all metadata
from the source material.
This is considered very important, since 1) For the lack of a prior
common file format for geodetic polynomial coefficients, there is a good
chance that this will become THE standard, at least for the time being,
and 2) Without the metadata represented, it will be very hard for a
human to debug code involving a slightly misrepresented polynomium.
Due to the current architecture of the pj_init.c code (mostly around the
fill_buffer() function), it is next to impossible to implement the line
continuation functionality in full generality. Hence, it has been
necessary to limit this format extension to files smaller than 64 kB.
* Correction of spherical HEALpix test case
The first HEALpix test case in nad/testvarious is clearly intended to
invoke the spherical form of HEALpix.
It does, however, specify the spheroid using the +a=1 size parameter,
without specifying any shape parameter.
But since +no_defs is not specified either, a shape parameter is picked
up from the nad/proj_def.dat file (where ellps=WGS84 is given in the
<general> section).
It appears that this has not happened before I updated the pj_init code to support projection
pipelines (see below). I do, however, believe that the present behaviour is the correct one,
and rather than retrohacking the pj_init code, to (incorrectly, I
believe) reproduce the prior behaviour, I have corrected the test case
invocation in nad/testvarious to specify the spheroid using the +R=1
size parameter (which was already used in the following test case).
* Repair scaling of projections stomping on value of semimajor axis
* Workaround MSVC HUGE_VAL misimplementation.
The "return const err object" idiom (i.e. const <type> err =
{HUGE_VAL,...}; ... if (bad) return err) is problematic to implement
due to MSVC's misimplementation of HUGE_VAL as a non-const.
Hence, we need to run-time initialize these. In the pj_inv functions,
this was mistakenly done to the wrong object.
For pj_fwdobs/invobs and the remaining part of the obs-based API, this
is now worked around by providing functions returning a run time
HUGE_VAL initialized PJ_OBS or PJ_COO resp.
Obnoxious, but given MSVC's market penetration there is really not much
else we can do.

facto standard M_PI and its ilk. Change names that are widely used in the project to be in the M_ namespace, so HALFPI becomes M_HALFPI. HALFPI is #defined as M_PI_2 (the defacto standard name). #defines _USE_MATH_DEFINES for MS Visual Studio (I didn't personally test this part, but Appveyor will not build otherwise).

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
