MOVEONLY: Move void UpdateTime() from pow.o to miner.o (plus fix include main.h -> chain.h)
CBlockIndex::GetBlockWork() + GetProofIncrement(nBits) -> GetBlockProof(CBlockIndex)
Port/fix txnmall.sh regression test

Ported txnmall.sh to Python, and updated to match
recent transaction malleability changes.

I also modified it so it tests both double-spending
confirmed and unconfirmed (only-in-mempool) transactions.

Renamed to txn_doublespend, since that is really what is
being tested. And told the pull-tester to run both
variations on this test.
Truthier error message when rpcpassword is missing
depends: Use pic for all linux dependencies

This avoids textrels, and matches previous gitian behavior.
depends: Add a package for qt4.6. Linux uses it by default.

We're not ready to switch to a static qt5 for Linux yet due to missing plugin
support. This adds a recipe for building a shared qt4 that we build and link
against, but don't distribute.

make USE_LINUX_STATIC_QT5=1 can be used to build static qt5 as before.
gitian: descriptors overhaul

Descriptors now make use of the dependencies builder, so results are cached.
A very new version (>= e9741525c) of Gitian should be used in order to take
advantage of caching.

[Qt] explicitly call proxy in GUI settings SOCKS5 proxy

- to ensure a consistent wording between core and GUI
Make STRICTENC invalid pubkeys fail the script rather than the opcode.

This turns STRICTENC turn into a softforking-safe change (even though it
is not intended as a consensus rule), and as a result guarantee that using
it for mempool validation only results in consensus-valid transactions in
the mempool.
Test the exact order of CHECKMULTISIG sig/pubkey evaluation

build: fix link error on some platforms. Fixes #5235

Some users may have libtool libs (.la) installed in their linker search paths.
In this case, using -static-libtool-libs would try to link in .a's instead of
shared libs. That would be harmless unless the .a was built in a way that
would break linking, like non-fpic.

What we really want is "-static" here. Despite its name, it's actually less
aggressive than -static-libtool-libs. It causes only internal libs to be linked
statically (libbitcoinconsensus is the one were'a after).
Port of wallet.sh to python (wallet.py).

Also included are minor edits to util.py to create a clean blockchain and add a parameter to gather_inputs to specify number of confirmations.
Edited rpc-tests to run python script not shell script.
