As part of the partial improvement to the POST reading
code I also added a max_post_size setting which defaults
to 1 MiB. POST inputs longer than that size get truncated.
This is separate to max_pastie_size, which is just the
size of one of the values in the POST data.
The token rule was matching even when the quoted_string
rule should have matched, which was preventing the "
stripping to work. In fact quoted_string was never being
used.
Also improve formatting of long lines.
Env reads environment variables from the list it receives
from main(), so I can also pass it a forged list now
without needing extra classes with sometimes-virtual methods
or other cruft.
Get raw environment variables directly from main().
Add code to split on '=' in cgi_environment_vars and only pick
the ones that are interesting, just as before.
