Any projects which want to use Hush code from now on will need to be licensed as
GPLv3 or we will send the lawyers: https://www.softwarefreedom.org/
Notably, Komodo (KMD) is licensed as GPLv2 and is no longer compatible to receive
code changes, without causing legal issues. MIT projects, such as Zcash, also cannot pull
in changes from the Hush Full Node without permission from The Hush Developers,
which may in some circumstances grant an MIT license on a case-by-case basis.
https://trac.torproject.org/projects/tor/ticket/14999 is tracking an encoding
bug with the Tor control protocol, where many of the QuotedString instances that
Tor outputs are in fact CStrings, but it is not documented which ones are which.
https://spec.torproject.org/control-spec section 2.1.1 provides a future-proofed
rule for handing QuotedStrings, which this commit implements.
