Extra patches for Electrum-NMC stable branches

[JeremyRand]

Some concerns have been raised by one of our funding sources about the slow progress getting patches merged to upstream Electrum. Due to this, Electrum-NMC's stable branches will begin carrying extra patches that have been submitted upstream but not yet merged upstream. The unstable bitcoin/auxpow/master branches will not carry those patches, in order to minimize merge conflicts when the patches eventually get merged upstream. This issue will track which patches are being carried in our stable branches, and link to the corresponding upstream PR's.

Status on relevant patches:

• Use cp_height for checkpoints spesmilo/electrum#5147 : Requires additional patches to work with AuxPoW.
• Add from_coins arg to payto/paytomany spesmilo/electrum#5432 : Should be applicable without issues.
• Build: create a .tar.xz archive spesmilo/electrum#5465 : Should be applicable without issues.
• Use SOCKSRandomAuth for stream isolation spesmilo/electrum#5470 : Depends on socks.py: Add SOCKSRandomAuth kyuupichan/aiorpcX#23 making it into a release tag; at this time we're not comfortable maintaining a fork of aiorpcX.
• Unit tests for Blockchain.verify_header spesmilo/electrum#5537 : Should be applicable without issues.
• Stream isolation for commands spesmilo/electrum#5574 : Should be applicable without issues.

@domob1812 Will adding these patches to Electrum-NMC stable branches cause any disruption to Xaya?

[domob1812]

@JeremyRand: I've not looked at them, but in general you should not be concerned about that. Electrum-NMC should do what is best for Namecoin, and I will worry about how that relates to Xaya.

[domob1812]

FYI, I've now looked at the patches in a bit more detail. The only one that is relevant for Xaya is spesmilo#5147. Xaya has continuous difficulty retargeting, and because of that needs a lot more information in checkpoints in order to be able to compute the following difficulty. But since your patch essentially simplifies checkpoint handling, it will probably also simplify Xaya's changes. Hence it will probably require some work on my side after merging, but will then probably make life easier in the long term.

spesmilo#5537 is merged upstream, so is being removed from this list.
