Merge bitcoin-core/secp256k1#1113 : build: Add CMake-based build system
...
e1eb33724c10602b00305468d70964https://cmake.org/ )-based build system.
Added build instructions and examples to the [`README.md`](https://github.com/hebasto/secp256k1/blob/220628-cmake/README.md#building-with-cmake-experimental ) file.
Ways to integrate with downstream CMake-based projects:
- if `secp256k1` is a subtree (including Bitcoin Core project) -- `add_subdirectory(secp256k1)`
- if `secp256k1` has been installed -- `find_package(secp256k1 0.2.1 CONFIG)`, see https://github.com/hebasto/secp256k1-CMake-example
Added a few toolchain files for easy cross compiling.

**Implementation notes**
Minimum required CMake version is 3.1. This was required to provide [`C_STANDARD`](https://cmake.org/cmake/help/latest/prop_tgt/C_STANDARD.html ) property.
In turn, this choice of CMake version implies it is not possible to build with default CMake on Debian 8, which has CMake v3.0.2 only.

examples: Extend sig examples by call that uses static context
...
Besides improving the examples, this makes sure that the examples
import a variable (instead of a function), namely the static context,
from the library. This is helpful when testing MSVC builds, because
the MSVC linker tends to be awkward when importing variables.
