* protect-tool.c: Include estream.h.
(store_private_key): Replace stdio streams by estream functions
for a portable use of the "x" mode.
* trustlist.c: Include estream.h.
(agent_marktrusted): Repalce stdio stream by estream functions.
* protect-tool.c (store_private_key): Use bin2hex.

* gpg-agent.c (main): Run pth_kill after fork. Fixes bug#1066.
