More disciplined use of 'errno'
...
Set errno to zero before calling any function where we may use its
errno, and check errno for zero before using it (as functions may not
set it even in error). The code assumes that no function will put
garbage on errno (although ISO C allows that): If any function during an
operation set errno, and the operation result in an error, assume that
errno has something to say.

'luaH_get' functions return tag of the result
...
Undoing previous commit. Returning TValue increases code size without
any visible gains. Returning the tag is a little simpler than returning
a special code (HOK/HNOTFOUND) and the tag is useful by itself in
some cases.

- Varint uses a type large enough both for size_t and lua_Unsigned.
- Most-Significant Bit 0 means last byte, to conform to common usage.
- (unrelated) Change in macro 'getaddr' so that multiplication is
by constants.

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.)

Small optimization in 'luaH_psetint'

part of a table, so 'luaH_psetint' checks for the common case that

Bug: Yielding in a hook stops in the wrong instruction
...
Yielding in a hook must decrease the program counter, because it already
counted an instruction that, in the end, was not executed. However,
that decrement should be done only when about to restart the thread.
Otherwise, inspecting the thread with the debug library shows it one
instruction behind of where it really is.
