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.

Stack reallocation done with a single realloc

at the same time, to correct the pointers to the stack, these pointers

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.)

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.
