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: remote: Don't change exit_code in program_client_remote_disconnect() when program_input is already NULL. When the program_input is NULL, the stream is finished, meaning that the exit_code is set based on the return code. There can be a program_input for remote streams, even when the program produces no output.

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

global: Use i_stream_read_memarea() wherever possible

global: Add flags parameter to i_stream_create() and set it to 0 This just changes the API - the following changes add the new flag.

global: start relying on timeout_remove(NULL) being a no-op Cleanup performed with the following semantic patch: @@ expression E; @@ - if (E != NULL) { - timeout_remove(&E); - } + timeout_remove(&E);

util: script: Increased the major protocol version due to earlier changes.

util: script: Amended protocol with the ability to convey a set of environment variables that are passed to the script. The acceptable environment variables are selected using the -e parameter; others are ignored silently.

util: script: Amended the protocol to pass arguments escaped to prevent problems with newlines. Newlines are used as argument delimiters in the protocol, which will cause problems.

spelling fixes

lib-program-client: Use net_ipport2str

lib-program-client: Retry connection on EAGAIN

program-client-unix: Don't retry connecting to UNIX socket. Especially with async connections this will just block the whole process when there are errors.

lib-program-client: Fixed boolean expressions. Problems found with clang -Wstrict-bool.

lib-program-client: Gave variables pointing to a program-client more logical names. Was still based on when it was called the script-client.

lib-program-client: Correctly handle error code

lib-program-client: Whitespace fixes

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

lib-program-client: Move version string to define

lib-program-client: Add TCP client support

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

lib-program-client: Disconnect asynchronously

lib-program-client: Rename remote to unix This is to make more clear that the call requires unix path and does not support TCP. There will be TCP based API too later.

lib-program-client: Expose asynchronous API

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