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

We are relying more and more on C99 math functions. On C89 systems where
those functions are not available our own custom versions of those
functions are used instead. So far these has been spread across the code
base. This commit gathers them in the same file and introduces the
proj_math.h header. The build system checks for C99 math functions. If
not found the proj_math.h header make sure that C99 functions are
defined as their pj_ equivalent.
Ideally proj_math.h is included instead of math.h. This removes the need
for any checks against HAVE_C99_MATH in the code making it easier to
read.
For this commit the functions hypot, log1p and asinh has been taken care
of.

lam0 of inf caused a nan in the cast to int.
Picked +/-1000 for lam0 as a guess for what constitutes reduculously large values.
proj_etmerc.c:361:16: runtime error: nan is outside the range of representable values of type 'int'
Found with autofuzz: UndefinedBehaviorSanitizer: float-cast-overflow

* 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

Some macros seemed to be leftover from earlier code, so I removed them.
Others seemed like they should have been used, but weren't.
There should be no functional change, except the following: in floating-
point arithmetic, x / y is not the same as x * (1.0 / y). It can be
argued that using the multiplication is significantly faster, and the
algorithm is approximative anyway. Otherwise, the constants are
obviously not required.
Also fixes one location in PJ_aitoff.c, where an enumeration value
should have been used.

* 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.

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

Add a test to check this. Output of an existing test changed in 7th
