Two changes:

Adds a -regtest-only-mode setmocktime timestamp RPC call that causes all subsequent internal GetTime() calls to return that time. This uses the same code as some of the unit tests; it will let us do more thorough testing of scenarios with peers that have different notions of the current time.

The last commit modifies the regression test initial blockchain (stored in the qa/rpc-tests/cache/ directory) so those blocks are created with fixed, known timestamps (will be important for code that tests difficulty adjustment / re-org scenarios).

Builds on #5275

Sigh... mingw32 and 64 were both failing, I pushed a no-change to get travis to re-run, now just one of them is failing (timing out during tests)...

@gavinandresen Until we get to the bottom of the flaky rpc tests w/ wine, you may want to pull in https://github.com/theuni/bitcoin/commit/bcf4cfe2f1a32bfa285ed34b9e334df434f146c3 .

RPC tests: create initial chain with specific timestamps

Use setmocktime to create the initial block chain with
10-minute-apart-blocks starting 1 Jan 2014.
