lib-program-client: Make an explicit enum for the exit code. Before, the meaning of the code was confusing, since the actual program returns a different set of values.

lib-program-client: Add comments to program_input/program_output functions.

lib-program-client: Flush/finish the output stream after o_stream_send_istream(). There may still be data in the output stream buffer. Failing to flush this leads to truncated output. For the output towards the program o_stream_finish() is used, since there may be an ostream_dot in between (or something else for future features).

lib-program-client: Simplify cleanup of dot input stream in program_client_program_input().

lib-program-client: Restructure reading input from program to simplify handling of dot input stream.

lib-program-client: Use reliable means of checking for input stream EOF.

lib-program-client: Remove check for -2 returned from i_stream_read_more(). The stream must have space for at least 1 byte.

lib-program-client: Remove useless stream eof check. It also looks to be problematic.

lib-program-client: Ignore ostream error handling

global: Rename i_stream_is_eof() to i_stream_read_eof() This describes its behavior a bit better.

lib-mail: ostream-dot - Require o_stream_finish() to write the trailer Similar to ostream-zlib.

lib-program-client: Clarify dot_input/dot_output NULL checks. Helps to avoid static analyzer false positives about NULL pointer dereference.

lib-program-client: Do not call program_client_fail twice Fixes crash in program-client caused by use of freed memory.

Updated copyright notices to include the year 2017.

lib-program-client: Do not call callback when destroying

lib-program-client: Remove code duplication The content is sent on connected already. Do not send it early in async connect.

lib-program-client: Change program_client_create() API to return error string.

lib-program-client: Deduplicate flush statement It can be done below by splitting the else if into separate if statement.

lib-program-client: Fix memory access problem

lib-program-client: Whitespace fixes

lib-program-client: Add support for iostream-dot This is also made mandatory for TCP client.

lib-program-client: Add URI based constructor

lib-program-client: Add switch_ioloop vfunc This lets program-client backends do their own special io loop switching.

lib-program-client: Use milliseconds in idle timeout

lib-program-client: Use child-wait This makes the client waiting asynchronous.

lib-program-client: Disconnect asynchronously

lib-program-client: Fixed program_client_run() that succeeds rapidly. program_client_run_async() could have called the callback with result=0 before io_loop_run(). This happened with local client. Fixes in test-program-client-local: Panic: BUG: No IOs or timeouts set. Not waiting for infinity.

lib-program-client: Expose asynchronous API

lib-program-client: Whitespace fix

lib-program-client: Add program-client from pigeonhole
