351ccd7332 Towards a new implementation of arrays 
The array part of a table wastes too much space, due to padding.
To avoid that, we need to store values in the array as something
different from a TValue. Therefore, the API for table access
should not assume that any value in a table lives in a *TValue.
This commit is the first step to remove that assumption: functions
luaH_get*, instead of returning a *TValue where the value lives,
receive a *TValue where to put the value being accessed.
(We still have to change the luaH_set* functions.)

09f3c2372f Option '-l' discards version sufix from file name 
Like 'require', the command-line option '-l' discards an optional
version suffix (everything after an hyphen) from a file name when
creating the module name.

6443185167 "Emergency" new version 5.4.6 
'lua_resetthread' is back to its original signature, to avoid
incompatibilities in the ABI between releases of the same version.
New function 'lua_closethread' added with the "correct" signature.

5a04f1851e New function 'luaL_makeseed' 
This function unifies code from 'lua_newstate', 'math.randomseed',
and 'table.sort' that tries to create a value with a minimum level
of randomness.
