llimits.h being used by all Lua code
...
The definitions in llimits.h are useful not only for the core. That
header only defines types and '#define's, so libs and core still do
not share any real code/data.

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.

Added macro 'luaL_pushfail'
...
The macro 'luaL_pushfail' documents all places in the standard libraries
that return nil to signal some kind of failure. It is defined as
'lua_pushnil'. The manual also got a notation (@fail) to document those
returns. The tests were changed to be agnostic regarding whether 'fail'
is 'nil' or 'false'.

Define LUA_MAXUNSIGNED as a preprocessor constant

The previous definition of LUA_MAXUNSIGNED used a typecast,
making it unsuitable for constant expressions in the preprocessor.

A few changes in tests about number of bits in integers
...
- The preprocessor must work with at least 'long', and therefore must
do shifts of up to 31 bits correctly.
- Whenever possible, use unsigned types in shifts.

'math.randomseed()' sets a somewhat random seed
...
When called with no arguments, 'math.randomseed' uses time and ASLR
to generate a somewhat random seed. the initial seed when Lua starts
is generated this way.

'math.rand()' uses higher bits to produce float value
...
The call 'math.rand()' converts the higher bits of the internal unsigned
integer random to a float, instead of its lower bits. That ensures that
Lua compiled with different float precisions always generates equal (up
to the available precision) random numbers when given the same seed.
