* agent/call-daemon.c (daemon_start): Decision of connection/reuse of
CTX and assignment to ->ctx should be done with the lock.

When scdaemon is exiting and agent tries to spawn/connect/reconnect,
there is a race condition between detecting finish of scd and
spawn/connect/reconnect.

These are non-substantive corrections for minor spelling mistakes
within the GnuPG codebase.
With something like this applied to the codebase, and a judiciously
tuned spellchecker integrated as part of a standard test suite, it
should be possible to keep a uniform orthography within the project.

It's for RSA PKCD#1 encoding if the decrypt operation removes padding
or not. When caller knows it's not RSA, this information is no use
and it is better to allow NULL with the variable R_PADDING.
