Push passes to another commands, as described in https://public-inbox.org/git/20171129032214.GB32345@sigill.intra.peff.net/ As it gets complicated to correctly track the data length, instead transfer the data through parent process and cut the pipe as the specified length is reached. Do it only when CONTENT_LENGTH is set, otherwise pass the input directly to the forked commands. Add tests for cases: * CONTENT_LENGTH is set, script's stdin has more data, with all combinations of variations: fetch or push, plain or compressed body, correct or truncated input. * CONTENT_LENGTH is specified to a value which does not fit into ssize_t.
