Previously, the progress bar had two subtly different states in which the bar
would not actually render, both with their own shortcomings: inactive (which
was irreversible) and paused (reversible, but swallowing logs). Furthermore,
there was no way of resetting the statistics, so a very bad solution was
implemented (243c0f18dae2a08ea0e46f7ff33277c63f7506d7) that would create a new
logger for each line of the repl, leaking the previous one and discarding the
value of printBuildLogs. Finally, if stderr was not attached to a TTY, the
update thread was started even though the logger was not active, violating the
invariant required by the destructor (which is not observed because the logger
is leaked).
In this commit, the two aforementioned states are unified into a single one,
which can be exited again, correctly upholds the invariant that the update
thread is only running while the progress bar is active, and does not swallow
logs. The latter change in behavior is not expected to be a problems in the
rare cases where the paused state was used before, since other loggers (like
the simple one) don't exhibit it anyway. The startProgressBar/stopProgressBar
API is removed due to being a footgun, and a new method for properly resetting
the progress is added.

These commands outputs data that may not end with a newline. This
causes problems when the progress bar redraws, as that completely
wipes the last line of output. As nix key generate-secret outputs
a single line of text with no output, it shows up entirely blank,
making it look like nothing happened.

Fixes #7939.

These were needed back in the pre-C++11 era because we didn't have
move semantics. But now we do.

This was useful for an experiment with building Nix as a single
compilation unit. It's not very useful otherwise but also doesn't
hurt...

This reverts commit f78126bfd6b6c8477fcdbc09b2f98772dbe9a1e7. There
really is no need for such a massive change...

For example,
$ NIX_REMOTE=file:///my-cache nix ls-store -lR /nix/store/f4kbgl8shhyy76rkk3nbxr0lz8d2ip7q-binutils-2.23.1
dr-xr-xr-x 0 ./bin
-r-xr-xr-x 30748 ./bin/addr2line
-r-xr-xr-x 66973 ./bin/ar
...
Similarly, "nix ls-nar" lists the contents of a NAR file, "nix
cat-nar" extracts a file from a NAR file, and "nix cat-store" extract
a file from a Nix store.
