Roberto Ierusalimschy 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.

Roberto Ierusalimschy 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.
