c259a7cbc0 Set precomputation table late and unset early. 
Set the global pointer to the precomputation table only after initializing
it completely, and unset it before doing any uninitialization.

This causes fail-fast behavior in case of race conditions between
initialization and operations using it.

Try to not leave secret data on the stack or heap. 
This makes a basic effort and has not been audited.
Doesn't appear to have a measurable performance impact on bench.

It also adds a secp256k1_num_free to secp256k1_ecdsa_pubkey_create.

7280781c3a travis: minimize the dependencies available for each build config 
This is a more realistic representation of a build environment. Helps to ensure
configure logic and that headers aren't accidentally assumed to be present.

3ab1178d54 build: grab full paths to host tools 
This ensures that make will work even if PATH has changed, which is often the
case when cross-compiling.

Fixes cross-compiled builds when integrated into Bitcoin's repo.
