131e3fd814 Avoid using 'signal' when 'sigaction' is available 
The semantics of 'signal' varies a lot among different implementations;
'sigaction' ensures a more consistent behavior.

69b71a6919 _PROMPT can have non-string values 
'get_prompt' uses 'luaL_tolstring' to convert _PROMPT or _PROMPT2
value to a string. That conversion may invoke a '__tostring'
metamethod.

be78aeae4c Default for warnings changed to "off" 
Warnings are mostly a tool to help developers (e.g., by showing hidden
error messages); regular users usually don't need to see them.

a1d8eb2743 Added control messages to warnings 
Added the concept of control messages to the warning system, plus the
implementation of the controls "@on"/"@off" to turn warnings on/off.
Moreover, the warning system in the test library adds some other
controls to ease the test of warnings.

faaf7e481f Removed use of 'rl_inhibit_completion' in 'lua.c' 
Some old systems (e.g., Mac OS X 10.4) do not define
'rl_inhibit_completion', even when line history is available.
Anyway, the user can configure this option externally, using '~/.inputrc'.

without a definition for 'size_t'.)

de3fd8ab83 Handling of LUA_PATH/LUA_CPATH moved from package library to stand 
alone interpreter (so that 'lua.c' concentrates all handling of
environment variables)

ed19fe766c added ';' at the end of "expression lines" ("return exp;") so that 
an extra ";" at the end is enough to stop Lua printing the result
("return exp;;" is not valid)
