d5212c13b0 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).

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.

d69789da1c Fix absence of 'system' in iOS
Despite claiming to be ISO, the C library in some Apple platforms
does not implement 'system'.

cfbe378f90 Small simplification in overflow check in 'getfield'
Subtracting a small non-negative int from a non-negative int cannot
overflow, and adding a non-negative int to INT_MIN cannot overflow.

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).

efcf24be0c 'luaL_execresult' does not assume -1 status as error
ISO C is silent about the return of 'system'. Windows sets 'errno' in
case of errors. Linux has several different error cases, with different
return values. ISO C allows 'system' to set 'errno' even if there are no
errors. Here we assume that a status==0 is success (which is the case
on several platforms), otherwise it is an error. If there is an error
number, gives the error based on it. (The worst a spurious 'errno'
can do is to generate a bad error message.) Otherwise uses the normal
results.

Corrected several small details: added 'const', adjusts in tabs x
spaces, removed unused #includes and #defines, misspellings, etc.

2fc6b55dae Removed resource-related "emergency collections"
New to-be-closed variables is a better way to ensure the proper release
of resources.

3d838f635c Added "emergency collection" to 'io.tmpfile' and 'os.tmpname'
These operations also can give errors for lack of resources, so they
also will try "emergency collections" in case of resource errors.
Because there are now two libraries with that kind of handling,
'resourcetryagain' was moved to the auxiliary library to be shared
by the libraries.

e885dee5ab File operations try an "emergency collection" when failing
If a file operation fails do to lack of resources (too many open
files or not enough memory), it does a full garbage collection and
tries the operation again. Lack of resources are "too many open
files" (process wise and system wise) and "not enough memory".
The code is full of '#if's because error codes are not part
of the standard ISO C.
