BUG/MINOR: init: Use a dynamic buffer to set HAPROXY_CFGFILES env variable
The HAPROXY_CFGFILES env variable is built using a static trash chunk, via a
call to get_trash_chunk() function. This chunk is reserved during the whole
configuration parsing. It is far too large to guarantee it will not be
reused during the configuration parsing. And in fact, it happens in the lua
code since the commit f67442efd ("BUG/MINOR: lua: warn when registering
action, conv, sf, cli or applet multiple times"), when a lua script is
loaded.
To fix the bug, we now use a dynamic buffer instead. And we call memprintf()
function to handle both the allocation and the formatting. Allocation errors
at this stage are fatal.
This patch should fix the issue #1041. It must be backported as far as 2.0.
