According to RFC3875, empty environment variable is equivalent to unset,
and for CONTENT_LENGTH it should mean zero body to read.
However, unset CONTENT_LENGTH is also used for chunked encoding to indicate
reading until EOF. At least, the test "large fetch-pack requests can be split
across POSTs" from t5551 starts faliing, if unset or empty CONTENT_LENGTH is
treated as zero length body. So keep the existing behavior as much as possible.
Add a test for the case.

Commit 6c213e863a ("http-backend: respect CONTENT_LENGTH for
receive-pack", 2018-07-27) adds a test which uses the non-portable
export construct. Replace it with "FOO=bar && export FOO" instead.

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.
