Note: although I hopefully fixed all the conflicts,
some tests are quite broken.
Conflicts:

every chunk has the encryption key type as first byte and we do not want to rewrite the whole repo
to change the passphrase type to repokey type. thus we simply dispatch this type to repokey
handler.
if there is a repokey that contains the same secrets as they were derived from the passphrase, it will just work.
if there is none yet, one needs to run migrate-to-repokey command to create it.
refactorings:
- introduced concept of default answer:
if the answer string is in the defaultish sequence, the return value of yes() will be the default.
e.g. if just pressing <enter> when asked on the console or if an empty string or "default" is
in the environment variable for overriding.
if an environment var has an invalid value and no retries are enabled: return default
if retries are enabled, next retry won't use the env var again, but either ask via input().
- simplify:
only one default - this should be a SAFE default as it is used in some special conditions
like EOF or invalid input with retries disallowed.
no isatty() magic, the "yes" shell command exists, so we could receive input even if it is not from a tty.
- clean:
separate retry flag from retry_msg
we use forking mode always and either execute python with the archiver module or the "borg.exe" binary.
the cmd fixture alternates between 'python' and 'binary' mode and calls exec_cmd accordingly.
Instead of "realistic data", I chose the test data to be either all-zero (all-ascii-zero to be precise)
or all-random and benchmark them separately.
So we can better determine the cause (deduplication or storage) in case we see some performance regression.
"help" is benchmarked to see the minimum runtime when it basically does nothing.
also:
- refactor archiver execution core functionality into exec_cmd() so it can be used more flexibly
- tox: usually we want to skip benchmarks, only run them if requested manually
- install pytest-benchmark - run tox with "-r" to have it installed into your .tox envs
