init: Avoid autoenabling special remotes that have control characters in their names
I'm on the fence about this. Notice that pulling from a git remote can
pull branches that have escape sequences in their names. Git will
display those as-is. Arguably git should try harder to avoid that.

But, names of remotes are usually up to the local user, and autoenable
changes that, and so it makes sense that git chooses to display control
characters in names of remotes, and so autoenable needs to guard against
it.

filter out control characters in all other Messages
This does, as a side effect, make long notes in json output not
be indented. The indentation is only needed to offset them
underneath the display of the file they apply to, so that's ok.

eliminate showStart showStartOther
These were not handling control characters and are redundant.

filter out control characters in warning messages
Converted warning and similar to use StringContainingQuotedPath. Most
warnings are static strings, some do refer to filepaths that need to be
quoted, and others don't need quoting.

Note that, since quote filters out control characters of even
UnquotedString, this makes all warnings safe, even when an attacker
sneaks in a control character in some other way.

When json is being output, no quoting is done, since json gets its own
quoting.

This does, as a side effect, make warning messages in json output not
be indented. The indentation is only needed to offset warning messages
underneath the display of the file they apply to, so that's ok.

filter out control characters in error messages
giveup changed to filter out control characters. (It is too low level to
make it use StringContainingQuotedPath.)

error still does not, but it should only be used for internal errors,
where the message is not attacker-controlled.

Changed a lot of existing error to giveup when it is not strictly an
internal error.

Of course, other exceptions can still be thrown, either by code in
git-annex, or a library, that include some attacker-controlled value.
This does not guard against those.

git style quoting for ActionItemOther
Added StringContainingQuotedPath, which is used for ActionItemOther.

In the process, checked every ActionItemOther for those containing
filenames, and made them use quoting.

full emulation of git filename escaping
Not yet used, but the plan is to make git-annex use this when displaying
filenames similar to how git does.
