* src/w32-io.c(_gpgme_io_spawn): Remove spawnhelper not found
diagnostic.
--
When spawnhelper is not found the error is now catched before
the CreateProcess call so the added diagnostic in bb2d11c
(which was not helpful because the value for spawnhelper
would be NULL in that case) is now no longer needed.
* src/w32-io.c (_gpgme_io_spawn): Show a message box in
case gpgme-w32spawn.exe not found.
--
Otherwise every engine call will just fail with unsupported
protocol. Even in the debug output the problem was not made
clear because CreateProcess will fail with error code 87
(Invalid Parameter) because spawnhelper is NULL. The helpful
error message for ERROR_INVALID_PARAMETER would have been:
"is 'NULL' correctly installed"
As GpgME basically becomes useless on Windows without the
spawnhelper we want to fail very loud in that case.

--
This bug has been with us since the support for gpgsm: If there is no
status line handler but a status line is received anyway the command
handling loop terminates and thus the command/answer order gets out of
sync. In the case of the bug report this is triggered by sending an
option which starts the agent and that starting emits a "PROGRESS"
status line.
The solution is not to stop reading after a status line but record a
possible error code and return that only after OK or ERR.

* src/sign.c (gpgme_op_sign_result): Test that invalid and valid

--
When invalid and valid signatures do not equal gpgme_signers_count() it
means that there was a bad passphrase during signing after the first
signer. This leaves the result.signatures from previous signers intact
which isn't correct since gpg will report:
gpg: number of one-pass packets does not match number of signature
packets
gpg: can't handle this ambiguous signature data
during verify. So when this happens append the valid signatures to the
.invalid_signers list with .reason set to GPG_ERR_GENERAL.

After a realloc (realloc is also used for initial alloc) the allocated

introduced by receiving data with different line lengths in a specific
order. This is not easy exploitable because libassuan constructs the
line. However a crash has been reported and thus it might be possible
to constructs an exploit.
