Construct a variable from
value and put it in the environment while saving the previous value of the environment variable into a global list so it can be restored later.
|const(char) ||the name of the variable|
|const(char) ||the value of the variable|
Allocate a new variable via xmalloc that can be added to the global environment. The resulting string will be null-terminated immediately after the end of the array.
|const(char) ||name of the variable|
|const(char) ||value of the variable|
Restore the original environment.
Save the environment variable
name if not saved already.
