ab859fe59b Bug: Loading a corrupted binary file can segfault 
The size of the list of upvalue names are stored separated from the
size of the list of upvalues, but they share the same array.

We still need access to a 16-bit system to correctly test
these changes.

02bab9fc25 Bug: Wrong line in error message for arith. errors 
It also causes 'L->top' to be wrong when the error happens,
triggering an 'assert'.

cf08915d62 New macro LUA_USE_IOS 
Do not try to detect automatically whether system is iOS; it is
simpler and more reliable to let the programmer inform that.

c888ae0aea Small changes in hash of pointers 
When converting from pointer to integer, use 'uintptr_t' if available;
otherwise try 'uintmax_t', and use 'size_t' as last resource.

314745ed84 Avoid excessive name pollution in test files 
Test files are more polite regarding the use of globals when locals
would do, and when globals are necessary deleting them after use.

ee645472eb Stack reallocation done with a single realloc 
To avoid the need of both the old and the new stack addresses valid
at the same time, to correct the pointers to the stack, these pointers
are changed to offsets before the reallocation and then changed back
to pointers after the reallocation.

overflow, and adding a non-negative int to INT_MIN cannot overflow.

69b77b6fde Changed the growth rate of string buffers 
The growth rate of string buffers was reduced from 2 to 1.5 (3/2).
As string buffers start larger (256~1024 bytes), they don't need to
grow that fast. Moreover, a lower rate allows multiplicative growth up
to larger sizes (3/2 of the maximum). (After that, the growth becomes
linear, which is mostly useless.)

997f11f543 Bug: 'break' may not properly close variable in a 'for' loop 
Function 'leaveblock' was generating "break" label before removing
variables from the closing block. If 'createlabel' created a 'close'
instruction (which it did when matching a goto/break that exited
the scope of an upvalue), that instruction would use the wrong level.

4a00f61276 'lua_checkstack' doesn't need to check stack overflow 
'luaD_growstack' already checks that. This commit also fixes an
internal bug in 'luaD_growstack': a large 'n' could cause an arithmetic
overflow when computing 'needed'.

42d40581dd Save stack space while handling errors 
Because error handling (luaG_errormsg) uses slots from EXTRA_STACK,
and some errors can recur (e.g., string overflow while creating an
error message in 'luaG_runerror', or a C-stack overflow before calling
the message handler), the code should use stack slots with parsimony.

This commit fixes the bug "Lua-stack overflow when C stack overflows
while handling an error".
