8b8d8eeae9 Remove travis_wait from lint script (Graham Krizek)
Pull request description:
Using the `travis_wait` command in conjunction with `set -o errexit` causes problems. The `travis_wait` command will correctly log the command's output if successful, but if the command fails the process exits before the `travis_wait` command can dump the logs. This will hide important debugging information like error messages and stack traces. We ran into this in #15196 and it was very hard to debug because output was being suppressed.
`travis_wait` was being used because the `contrib/verify-commits/verify-commits.py` script can sometimes run for a long time without producing any output. If a script runs for 10 minutes without logging anything, the CI run times out. The `travis_wait` command will extend this timeout by logging a message for you, while sending stderr and stdout to a file.
This PR removes the `travis_wait` command from our CI system and adds additional logging to the `verify-commits.py` script so it doesn't make Travis timeout.

Removing the 'universal_newlines' and 'encoding' args from the subprocess.check_outputs fuction. 'universal_newlines' is supported in 3.4, but 'encoding' is not. Without specifying 'encoding' it will make a guess at encoding, which can break things on BSD systems. We must handle encoding/decoding ourselves until we can use Python 3.6
45842c3d2 Improve documentation for running verify-commits.py script (Jameson Lopp)
Pull request description:
I ran into 3 different issues while trying to run the verify-commits script for the first time and I think documenting them would help save time for future developers.
1. I was trying to just run it with "python" and didn't realize I had multiple python versions installed and this script is only syntactically valid for python 3.x.
2. I needed to import the trusted keys
3. The script was hanging because it was triggering my yubikey for signature verification

Pull request description:
~~Make sure `LC_ALL=C` is set when using `grep` range expressions.~~
Make sure `LC_ALL=C` is set in all shell scripts.
From the `grep(1)` documentation:
> Within a bracket expression, a range expression consists of two characters separated by a hyphen. It matches any single character that sorts between the two characters, inclusive, using the locale's collating sequence and character set. For example, in the default C locale, `[a-d]` is equivalent to `[abcd]`. Many locales sort characters in dictionary order, and in these locales `[a-d]` is typically not equivalent to `[abcd]`; it might be equivalent to `[aBbCcDd]`, for example. To obtain the traditional interpretation of bracket expressions, you can use the C locale by setting the `LC_ALL` environment variable to the value C.

577f111 Make verify-commits.sh test that merges are clean (Pieter Wuille)
Pull request description:
Unsure if we want this.
This modifies verify-commits.sh to redo all merges along the leftmost commit branch (which includes all PR merges), and verify whether they match the merge commit's trees.
The benefit is that it will detect a case where one of the maintainers merges a PR, but makes an unrelated change inside the merge commit. This on itself is not very strong, as unrelated changes can also be included in the merged branch itself - but perhaps the merge commit is not something that people are otherwise likely to look at.
Fixes#8089

This reverts commit 7deba93bdc.
This is neither a "test" change, nor should the trusted-git-root
have been updated - there is a process for expired PGP keys.

Specifically, require that the left branch (first restult of git
show -s --format=format:%P) is a signed merge commit, instead of
allowing either. This is fine for now, but might need to be relaxed
in the future.
Also fixes an out-of-file-descriptors issue by holding too many
open FDs writing to /dev/null
Now that the trusted root is past all commits signed by that key we don't need
it in the trusted-keys list, nor do we need to whitelist those commits in
allow-revsig-commits
Any attacker who managed to make an evil commit that changed something in the
contrib/verify-commits/ directory could just as easily remove the warning
and/or modify it to not display the evil commits; telling the user to check
those commits specifically misleads them into checking just those commits
rather than the script itself.
