Rename account to label where appropriate
This change only updates strings and adds RPC aliases, but should simplify the implementation of address labels in https://github.com/bitcoin/bitcoin/pull/7729, by getting renaming out of the way and letting that change focus on semantics.
The difference between accounts and labels is that labels apply only to addresses, while accounts apply to both addresses and transactions (transactions have "from" and "to" accounts). The code associating accounts with transactions is clumsy and unreliable so we would like get rid of it.

* Z is the zone designator for the zero UTC offset.
* T is the delimiter used to separate date and time.
This makes it clear for the end-user that the date/time logged is
specified in UTC and not in the local time zone.

Pull request description:
This implements a minimum viable implementation of SegWit wallet support, based on top of #11389, and includes part of the functionality from #11089.
Two new configuration options are added:
* `-addresstype`, with options `legacy`, `p2sh`, and `bech32`. It controls what kind of addresses are produced by `getnewaddress`, `getaccountaddress`, and `createmultisigaddress`.
* `-changetype`, with the same options, and by default equal to `-addresstype`, that controls what kind of change is used.
All wallet private and public keys can be used for any type of address. Support for address types dependent on different derivation paths will need a major overhaul of how our internal detection of outputs work. I expect that that will happen for a next major version.
The above also applies to imported keys, as having a distinction there but not for normal operations is a disaster for testing, and probably for comprehension of users. This has some ugly effects, like needing to associate the provided label to `importprivkey` with each style address for the corresponding key.
To deal with witness outputs requiring a corresponding redeemscript in wallet, three approaches are used:
* All SegWit addresses created through `getnewaddress` or multisig RPCs explicitly get their redeemscripts added to the wallet file. This means that downgrading after creating a witness address will work, as long as the wallet file is up to date.
* All SegWit keys in the wallet get an _implicit_ redeemscript added, without it being written to the file. This means recovery of an old backup will work, as long as you use new software.
* All keypool keys that are seen used in transactions explicitly get their redeemscripts added to the wallet files. This means that downgrading after recovering from a backup that includes a witness address will work.
These approaches correspond to solutions 3a, 1a, and 5a respectively from https://gist.github.com/sipa/125cfa1615946d0c3f3eec2ad7f250a2. As argued there, there is no full solution for dealing with the case where you both downgrade and restore a backup, so that's also not implemented.
`dumpwallet`, `importwallet`, `importmulti`, `signmessage` and `verifymessage` don't work with SegWit addresses yet. They're remaining TODOs, for this PR or a follow-up. Because of that, several tests unexpectedly run with `-addresstype=legacy` for now.

This introduces two command line flags (-addresstype and -changetype) which control
the type of addresses/outputs created by the GUI and RPCs. Certain RPCs allow
overriding these (`getnewaddress` and `getrawchangeaddress`). Supported types
are "legacy" (P2PKH and P2SH-multisig), "p2sh-segwit" (P2SH-P2WPKH and P2SH-P2WSH-multisig),
and "bech32" (P2WPKH and P2WSH-multisig).
A few utility functions are added to the wallet to construct different address type
and to add the necessary entries to the wallet file to be compatible with earlier
versions (see `CWallet::LearnRelatedScripts`, `GetDestinationForKey`,
`GetAllDestinationsForKey`, `CWallet::AddAndGetDestinationForScript`).

- add static verifySize() function to PaymentServer and move the logging
on error into the function
- also use the new function in the unit test
- the function checks if the size is allowed as per BIP70
QT_NO_KEYWORDS prevents Qt from defining the `foreach`, `signals`,
`slots` and `emit` macros.
Avoid overlap between Qt macros and boost - for example #undef hackiness
in #6421.

This makes it easier for us to replace it if desired, since it's now only in
one spot. Also, it avoids the openssl include from allocators.h, which
essentially forced openssl to be included from every compilation unit.
Bitcoin amounts are stored as uint64 in the protobuf messages (see
paymentrequest.proto), but CAmount is defined as int64_t. Because
of that we need to verify that single and accumulated amounts are
in a valid range and no variable overflow has happened.
- fixes#5624 (#5622)
Thanks @SergioDemianLerner for reporting that issue and also supplying us
with a possible solution.
- add static verifyAmount() function to PaymentServer and move the logging
on error into the function
- also add a unit test to paymentservertests.cpp
- now logs if -rootcertificates="" was used to disable payment request
authentication via X.509 certificates
- also logs which file is used as trusted root cert, if -rootcertificates
is set
- this is based on #4122 (which can be closed)
Currently a payment request is only checked for expiration upon receipt.
It should be checked again immediately before sending coins to prevent
the user from paying to an expired invoice which would then require a
customer service interaction.
- add static verifyExpired() function to PaymentServer to be able to use
the same validation code in GUI and unit-testing code
- extend unit tests to use that function and also add an unit test which
overflows, because payment requests allow expires as uint64, whereas we
use int64_t for verification of expired payment requests
