transport-helper: clarify *:* refspec

The *:* refspec doesn't work, and never has, clarify the code and
documentation to reflect that. This in effect reverts commit 9e7673e
(gitremote-helpers(1): clarify refspec behaviour).

transport-helper: update refspec documentation

The refspec capability is not only used by 'import', also by
'export', and it's recommended in both.

transport-helper: clarify pushing without refspecs

This has never worked, since it's inception the code simply skips all
the refs, essentially telling fast-export to do nothing.

Let's at least tell the user what's going on.

transport-helper: warn when refspec is not used

For the modes that need it. In the future we should probably error out,
instead of providing half-assed support.

The reason we want to do this is because if it's not present, the remote
helper might be updating refs/heads/*, or refs/remotes/origin/*,
directly, and in the process fetch will get confused trying to update
refs that are already updated, or older than what they should be. We
shouldn't be messing with the rest of git.

transport-helper: trivial code shuffle

Just shuffle the die() part to make it more explicit, and cleanup the
code-style.

transport-helper: update remote helper namespace

When pushing, the remote namespace is updated correctly
(e.g. refs/origin/master), but not the remote helper's
(e.g. refs/testgit/origin/master), which currently is only
updated while fetching.

Since the remote namespace is used to tell fast-export which commits
to avoid (because they were already imported/exported), it makes
sense to have them in sync so they don't get generated twice. If the
remote helper was implemented properly, they would be ignored, if
not, they probably would end up repeated.

git-gc.txt, git-reflog.txt: document new expiry options

Document the new values that can be used for expiry values where their
use makes sense:

* git reflog expire --expire=[all|never]
* git reflog expire --expire-unreachable=[all|never]
* git gc --prune=all

Other combinations aren't useful and therefore no documentation is
added (even though they are allowed):

* git gc --prune=never

  is redundant with "git gc --no-prune"

* git prune --expire=all

  is equivalent to providing no --expire option

* git prune --expire=never

  is a NOP

Merge branch 'ap/strbuf-humanize' into jch

Teach "--human-readable" aka "-H" option to "git count-objects" to
show various large numbers in Ki/Mi/GiB scaled as necessary.

I've decided to let this topic supersede mc/count-objects-kibibytes.
Human users will get an even easier output with "-H" and by not
changing the output without an explicit option we do not have to
break third-party tools that may have been reading from the output
of this command.

* ap/strbuf-humanize:
  count-objects: add -H option to humanize sizes
  strbuf: create strbuf_humanise_bytes() to show byte sizes
