Use a global static context in fuzzing, reducing overhead

Reduce cryptography usage in --cfg=fuzzing
...
This reduces the usage of real cryptography in --cfg=fuzzing,
specifically replacing the secret->public key derivation with a
simple copy and ECDH with XOR of the public and private parts
(plus a stream of 1s to make a test pass that expected non-0
output).
It leaves secret tweak addition/multiplication as-is.
It also changes the context creation to over-allocate and store
the context flags at the end of the context buffer, allowing us
to easily test context flags in each function.
While it would be nice to have something fancier (eg XOR-based),
its not immediately obvious how to accomplish this, and better to
fix the issues I have than spend too much time on it.
Fixes #271 .

Do not test secret->public derivation or pk validity in fuzzing cfg
...
In the next commit the secret->public key derivation in fuzzing cfg
is changed to be simpler, as well as the validity rules of public
keys relaxed.
This adds a new test to ensure random keys can be added, not just
the hard-coded keys test that exists today.

Add a global-context-less-secure feature which skips randomization
...
This is useful for us downstream as we wish to target WASM with a
global context, and using rand in such a build doesn't seem like a
safe idea.

Reduce visibility on secp-sys symbols
...
cc-rs builds C dependencies with reduced visibility to avoid
exporting the C symbols all the way out to any rust-built shared
libraries however we override it with SECP256K1_API. We should
avoid doing this, allowing LTO/DCE to do its work.

Manually test that panicking from C will abort the process
...
Panicking from C is not UB in newer rust versions and will reliably
trigger an abort (without unwinding). In older rust versions, it is
technically UB but empirically it seems to "just work" (and what should
it realistically do except crashing, which is what we intent).
Since there's potentially no unwinding, we can't test this behavior
using [should_panic]. This PR will instead check the libtest output
explicitly in our CI tests.
Fixes #228 .

There is little reason to pull in the `rand` dep just for the `Rng`
trait for users who want to randomize contexts. We should expose a
randomize function that just takes 32 bytes.
