14edd364c3 Function 'warn' is vararg 
Instead of a 'tocont' flag, the function 'warn' in Lua now receives all
message pieces as multiple arguments in a single call. Besides being
simpler to use, this implementation ensures that Lua code cannot create
unfinished warnings.

b56d4e570a Changes in the warning system 
- The warning functions get an extra parameter that tells whether
message is to be continued (instead of using end-of-lines as a signal).

- The user data for the warning function is a regular value, instead
of a writable slot inside the Lua state.

437a5b07d4 Added a warning system to Lua 
The warning system is just a way for Lua to emit warnings, messages
to the programmer that do not interfere with the running program.

3b06f983ae Details 
- in 'luaB_tonumber', do not need to "checkany" when argument
is a number.

- in 'lua_resume', the call to 'luaD_rawrunprotected' cannot return
a status equal to -1.

46beca5bed Better error messages for some polymorphic functions 
New auxiliary functions/macros 'luaL_argexpected'/'luaL_typeerror'
ease the creation of error messages such as

  bad argument #2 to 'setmetatable' (nil or table expected, got boolean)

(The novelty being the "got boolean" part...)

72d82a296c revamping the incremental collector 
Some simplifications (not counting bytes, couting only slots visited;
no more 'gcfinnum'); more GC parameters; using vararg in 'lua_gc' to
set parameters in different GC modes

dbb6f11e8e bug (with compat on): 'ipairs' can work with any type that provides 
an __index; so, 'pairsmeta' should not check for tables. ('pairs'
already checks for tables through 'next'.)
