a08d82eb13 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.

9fa63a6268 Some 'unsigned int' changed to 'unsigned' 
'unsigned int' is too long sometimes. (We already write 'long' instead
of 'long int'...)

52aa2b5d24 Details 
- 'unsigned int' -> 'unsigned'
- Some explicit casts to avoid warnings
- Test avoids printing the value of 'fail' (which may not be nil)

0c9bec0d38 Better handling of size limit when resizing a table 
Avoid silent conversions from int to unsigned int when calling
'luaH_resize'; avoid silent conversions from lua_Integer to int in
'table.create'; MAXASIZE corrected for the new implementation of arrays;
'luaH_resize' checks explicitly whether new size respects MAXASIZE.
(Even constructors were bypassing that check.)

3e9dbe143d New function 'table.create' 
Creates a table preallocating memory. (It just exports to Lua the API
function 'lua_createtable'.)

86e8039a72 Clock component removed from 'luaL_makeseed' 
'clock' can be quite slow on some machines.

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.

deac067ed3 Avoid overflows when incrementing parameters in C 
Any C function can receive maxinteger as an integer argument, and
therefore cannot increment it without some care (e.g., doing unsigned
arithmetic as the core does).

59c88f846d Broadening the use of branch hints 
More uses of macros 'likely'/'unlikely' (renamed to
'l_likely'/'l_unlikely'), both in range (extended to the
libraries) and in scope (extended to hooks, stack growth).

- Fixed some warnings about unused values in comma expressions.
- Comments.

d12262068d Small optimizations in range checks 
Checks of the form '1 <= x && x <= M' were rewritten in the form
'(unsigned)x - 1 < (unsigned)M', which is usually more efficient.
(Other similar checks have similar translations.) Although
some compilers do these optimizations, that does not happen
for all compilers or all cases.
