Aurelien DARRAGON 29b6d8af16 MINOR: hlua: rename "tune.lua.preserve-smp-bool" to "tune.lua.bool-sample-conversion"
A better name was found for the option implemented in ec74438
("MINOR: hlua: add option to preserve bool type from smp to lua")

Indeed, "tune.lua.preserve-smp-bool {on | off}" wasn't explicit enough
nor did it encourage the adoption of the new "fixed" behavior (vs
historical behavior which is now considered as a bug).

Thus it becomes "tune.lua.bool-sample-conversion { normal | pre-3.1-bug }"
which actively encourage users to switch the new behavior after having
patched in-use Lua script if needed. From a technical point of view,
the logic remains the same, as the option currently defaults to
"pre-3.1-bug" to prevent script breakage, and a warning is emitted if
the option isn't set explicily and Lua is used.

Documentation and regtests were updated.

Must be backported in 3.1 with ec74438 and f2838f5 ("REGTESTS: fix
lua-based regtests using tune.lua.smp-preserve-bool")

# commit 70d318c
# BUG/MEDIUM: lua: possible CLOSE-WAIT state with '\n' headers
#
# The Lua parser doesn't takes in account end-of-headers containing
# only '\n'. It expects always '\r\n'. If a '\n' is processes the Lua
# parser considers it miss 1 byte, and wait indefinitely for new data.
#
# When the client reaches their timeout, it closes the connection.
# This close is not detected and the connection keep in CLOSE-WAIT
# state.
#
# I guess that this patch fix only a visible part of the problem.
# If the Lua HTTP parser wait for data, the timeout server or the
# connectio closed by the client may stop the applet.
