Two minor memory-leak fixes on 0.74 seem not to be needed on master:
the fix in an early exit path of pageant_add_keyfile is done already
on master in a different way, and the missing sfree(fdlist) in
uxsftp.c is in code that's been completely rewritten in the uxcliloop
refactoring.
Other minor conflicts: the rework in commit b52641644905 of
ssh1login.c collided with the change from FLAG_VERBOSE to
seat_verbose(), and master and 0.74 each added an unrelated extra
field to the end of struct SshServerConfig.
