[RFC PATCH v3 0/8] Remote helpers smart transport extensions

Changes from v2 to v3:

- Rename "FALLBACK" -> "fallback"
- Get rid of magic "layer6 ready" return
- Initialize paths when called as foo::bar://
- Remove dead code as NULL remote can't happen
- Move the stream dupping from unknown protocols patch to taking over
  transports patch (that one needs it)
- Reorder the series so that debugging and mandatory cap patches are
  first.
- Rename virtual_connected to got_remote_heads (that's what it is)
- Coding style fix ups
- Move transport connect code from smart transports to archive patch.

Ilari Liusvaara (8):
  Add remote helper debug mode
  Support mandatory capabilities
  Pass unknown protocols to external protocol handlers
  Refactor git transport options parsing
  Support taking over transports
  Support remote helpers implementing smart transports
  Support remote archive from external protocol helpers
  Remove special casing of http, https and ftp
