This eliminates the use of MBEDTLS_PRIVATE in sample programs to access
fields of an mbedtls_ecp_keypair structure.
When displaying elliptic curve points, the program now display the
coordinates in the standard form instead of the internal representation.
The auxiliary function show_ecp_key is present in three programs. It's more
complex than the previous code which was also triplicated. There's no good
place for such auxiliary functions that don't belong in the library and are
used in multiple sample programs.

Directly export the public part of a key pair without having to go through
intermediate objects (using mbedtls_ecp_point_write_binary would require a
group object and a point object).

Set the public key in a key pair. This complements mbedtls_ecp_read_key and
the functions can be used in either order.
Document the need to call check functions separately.

Sometimes you don't need to have all the parts of a key pair object. Relax
the behavior of mbedtls_ecp_keypair so that you can extract just the parts
that you need.

Add a simple function to get the group id from a key object.
This information is available via mbedtls_ecp_export, but that function
consumes a lot of memory, which is a waste if all you need is to identify
the curve.

This reverts commit be978a8c4f.
The feature is no longer needed, and the script is broken if you don't pass
--make-vars.

When building with Make on a Unix-like platform (shell and compiler),
auto-detect configurations that may require linking with pthread.
This removes the need for MAKE_THREADING_FLAGS in all.sh.

Create a common.make for definitions that are shared between tests/Makefile
and programs/Makefile, to facilitate maintenance. Start populating it with
CFLAGS/LDFLAGS variables. More to follow in subsequent commits.
Keep library/Makefile independent, at least for the time being.

Unify the treatment of MBEDTLS_TEST_OBJS between programs/Makefile and
tests/Makefile: include it via LOCAL_LD_FLAGS in both cases. Document why
the definition of MBEDTLS_TEST_OBJS is different.
