getenv_allocating()

logical function matrixelements_hydrogenic::getenv_allocating	(	character(*), intent(in)	variable_name,
		character(:), intent(inout), allocatable	value
	)

Fetches an environment variable.

If it was able to fetch the variable value, returns .true. and sets value to the value ([re]allocating if necessary). Returns .false. if the variable is not defined

Under the hood it calls get_environment_variable, but it properly allocates or re-allocates the value to match the actual length of the environment variable.

TODO: For this to be a proper library function, it should be implemented as an interface with additional methods to handle pointers and fixed-length strings.

NOTE: It appears that this implementation does not work with GFortran 4.8 and 4.9, probably due to a compiler bug (value in the caller context does not get set properly, even though it looks fine in getenv_allocating). It works with GFortran 5.5.0, but it is unknown if which 5.x version fixed the issue.
