Always create 70 byte signatures with low R values
...
When extra entropy is not specified by the caller, CKey::Sign will
now always create a signature that has a low R value and is at most
70 bytes. The resulting signature on the stack will be 71 bytes when
the sighash byte is included.
Using low R signatures means that the resulting DER encoded signature
will never need to have additional padding to account for high R
values.

wallet: Get rid of LockObject and UnlockObject calls in key.h
...
Replace these with vectors allocated from the secure allocator.
This avoids mlock syscall churn on stack pages, as well as makes
it possible to get rid of these functions.
Please review this commit and the previous one carefully that
no `sizeof(vectortype)` remains in the memcpys and memcmps usage
(ick!), and `.data()` or `&vec[x]` is used as appropriate instead of
&vec.

Update key.cpp to use new libsecp256k1
...
libsecp256k1's API changed, so update key.cpp to use it.
Libsecp256k1 now has explicit context objects, which makes it completely thread-safe.
In turn, keep an explicit context object in key.cpp, which is explicitly initialized
destroyed. This is not really pretty now, but it's more efficient than the static
initialized object in key.cpp (which made for example bitcoin-tx slow, as for most of
its calls, libsecp256k1 wasn't actually needed).
This also brings in the new blinding support in libsecp256k1. By passing in a random
seed, temporary variables during the elliptic curve computations are altered, in such
a way that if an attacker does not know the blind, observing the internal operations
leaks less information about the keys used. This was implemented by Greg Maxwell.
