When extra entropy is not specified by the caller, CKey::Sign will
now always create a signature that has a low R value and is at most
70 bytes. The resulting signature on the stack will be 71 bytes when
the sighash byte is included.
Using low R signatures means that the resulting DER encoded signature
will never need to have additional padding to account for high R
values.
23fbbb100f wallet: sum ancestors rather than taking max in output groups (Karl-Johan Alm)
Pull request description:
This is pointed out in https://github.com/bitcoin/bitcoin/pull/12257#discussion_r204549758.
Basically, the ancestors gives an indication as to how many ancestors the resulting transaction will have, which is more precise when summing up the values, rather than taking the maximum, since all the coins in the group will become ancestors if selected.

a1a998cf24 wallet: Fix backupwallet for multiwallets (Daniel Kraft)
Pull request description:
`backupwallet` was broken for multiwallets in their own directories (i.e. something like `DATADIR/wallets/mywallet/wallet.dat`). In this case, the backup would use `DATADIR/wallets/wallet.dat` as source file and not take the specific wallet's directory into account.
This led to either an error during the backup (if the wrong source file was not present) or would silently back up the wrong wallet; especially the latter behaviour can be quite bad for users.

This also adds a generic qt linux target in packages.mk . I am a bit confused by the existing docs for the RISC addition. Are there boards that would support running bitcoin-qt, or at the very least forwarding X over ssh? Is everybody building depends with `NO_QT=1` when targeting RISC? If not, I will revert the change for a generic qt linux package definition back to the piecemeal solution.

566f826902 use only travis jobs: instead of mix of jobs+matrix (Julian Fleischer)
Pull request description:
This is extracted from https://github.com/bitcoin/bitcoin/pull/13816 to make that one simpler.
The travis `matrix` and `jobs` top level items are actually aliases for each other. The goal is to be able to specify not just the environment per job but also the `os` (for https://github.com/bitcoin/bitcoin/pull/13816 ). So this PR moves the environment variables from the `env.matrix` section to `jobs.include`.
`jobs` and build stages subsume the matrix functionality. IMHO this makes it clearer to add stages (as every item clearly references which stage it belongs to).
The `before_install`, `install`, etc. steps default to belonging to the `test` stage and were moved up .

4a43306a4f gui: Reject edit address dialog when key escape is pressed (João Barbosa)
f7a553177d gui: Add GUIUtil::ItemDelegate with keyEscapePressed signal (João Barbosa)
Pull request description:
Currently `EditAddressDialog` and `OptionsDialog` don't close when the escape key is pressed. The `QDataWidgetMapper` instances prevents closing the dialogs because the escape key is used to reset the widgets values. More details and workarounds in https://stackoverflow.com/a/51487847 and http://qtramblings.blogspot.com/2010/10/qdatawidgetmapper-annoyances.html.
The adopted solution is different from the above references. It turns out that `QDataWidgetMapper::setItemDelegate` sets the event filter for all mapped widgets. So in this PR the mapper's delegate are changed to a custom `GUIUtil::ItemDelegate` that offers the signal `keyEscapePressed`, which is connected to the `QDialog::reject` slot.
Note that the installed event filter lets all events pass, so the current behaviour isn't changed, meaning that widgets values are reset in addition to closing the dialog.

return InitError(strprintf(_("Prune configured below the minimum of %d MiB. Please use a higher number."), MIN_DISK_SPACE_FOR_BLOCK_FILES / 1024 / 1024));

So correct value of nPruneTarget is **greater than or equal to** MIN_DISK_SPACE_FOR_BLOCK_FILES.

9994d01d8b Add Unit Test for SingleThreadedSchedulerClient (Jesse Cohen)
Pull request description:
As discussed in #13023 I've split this test out into a separate pr
This test (and documentation update) makes explicit the guarantee (previously undefined, but implied by the 'SingleThreaded' in `SingleThreadedSchedulerClient()`) - that callbacks pushed to the `SingleThreadedSchedulerClient()` obey the single threaded model for memory and execution - specifically, the callbacks are executed fully and in order, and even in cases where a subsequent callback is executed by a different thread, sequential consistency of memory for all threads executing these callbacks is maintained.
Maintaining memory consistency should make the api more developer friendly - especially for users of the validationinterface. To the extent that there are performance implications from this decision, these are not currently present in practice because all use of this scheduler happens on a single thread currently, furthermore the lock should guarantee consistency across callback executions even when callbacks are executed by multiple threads (as the test does).
