PROJ/src/cs2cs.c, branch azp

Rename cs2cs.c to cs2cs.cpp with minimal changes to make it compile

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.

cs2cs: Always convert to degrees when angular output is received (#1112)

2018-09-07T21:37:22+00:00

Previous to this commit cs2cs did not convert angular output to degrees
when using operations setting PJ->right = PJ_IO_UNITS_ANGULAR. This
commit adopts the conventions used after the introduction of pipelines.

In practice, this allows the following and similar transformations to
output in degrees and not radians:

```
echo 37.3916666667   -6.9325000 | cs2cs +proj=latlong +ellps=clrk80 \
    +to +proj=molodensky +ellps=clrk80 +da=-112.145 +df=-0.54750714e-4 \
    +dx=-175 +dy=-23 +dz=-303
37.39   -6.93 -8.2
```

Add -d option to proj, cs2cs and cct (#1109)

2018-09-05T20:17:10+00:00

Specify number of decimals to display when transforming coordinates with either proj, cs2cs or cct.

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.
