If ZMQ is enabled, check whether it's installed before running ZMQ tests.
If it isn't, disable ZMQ and print a warning.
Also add dependency info to test docs, so users know ZMQ is required
before running tests, and so they know how to install it.
When following the build instructions before this change then trying
to run the RPC tests, a unix user would get an error when python
tried to import zmq.
There may be other dependencies that should be added to the docs,
particularly ones for non-unix systems. This is the only unlisted
dependency I encountered using linux.
In rpc-tests.py, don't override BITCOIND and BITCOINCLI if they're
already set. Makes it possible to run the tests with either another tree
or the GUI.
This replaces using inv messages to announce new blocks, when a peer requests
(via the new "sendheaders" message) that blocks be announced with headers
instead of inv's.
Since headers-first was introduced, peers send getheaders messages in response
to an inv, which requires generating a block locator that is large compared to
the size of the header being requested, and requires an extra round-trip before
a reorg can be relayed. Save time by tracking headers that a peer is likely to
know about, and send a headers chain that would connect to a peer's known
headers, unless the chain would be too big, in which case we revert to sending
an inv instead.
Based off of @sipa's commit to announce all blocks in a reorg via inv,
which has been squashed into this commit.

1) created rpc-tests.py
2) deleted rpc-tests.sh
3) travis.yml points to rpc-tests.py
4) Modified Makefile.am
5) Updated README.md
6) Added tests_config.py and deleted tests-config.sh
7) Modified configure.ac with script to set correct path in tests_config.py
Associate with each CTxMemPoolEntry all the size/fees of descendant
mempool transactions. Sort mempool by max(feerate of entry, feerate
of descendants). Update statistics on-the-fly as transactions enter
or leave the mempool.
Also add ancestor and descendant limiting, so that transactions can
be rejected if the number or size of unconfirmed ancestors exceeds
a target, or if adding a transaction would cause some other mempool
entry to have too many (or too large) a set of unconfirmed in-
mempool descendants.
In txn_clone.py, non-essential test transaction tx2 was asserted
to be unconfirmed, but would occasionally confirm depending on
network behavior. Fix by explicitly sharing with miner and
checking for 1 confirmation.
Reduce required conflict tests from 4 to 2, by moving one invocation
each of txn_clone.py and txn_doublespend.py to the extented test
section. This saves about 15 seconds per test run for me.
