remote-curl: unquote incoming push-options
The transport-helper protocol c-style quotes the value of
any options passed to the helper via the "option <key> <value>"
directive. However, remote-curl doesn't actually unquote the
push-option values, meaning that we will send the quoted
version to the other side (whereas git-over-ssh would send
the raw value).
The pack-protocol.txt documentation defines the push-options
as a series of VCHARs, which excludes most characters that
would need quoting. But:
1. You can still see the bug with a valid push-option that
starts with a double-quote (since that triggers
quoting).
2. We do currently handle any non-NUL characters correctly
in git-over-ssh. So even though the spec does not say
that we need to handle most quoted characters, it's
nice if our behavior is consistent between protocols.
There are two new tests: the "direct" one shows that this
already works in the non-http case, and the http one covers
this bugfix.
