split from env_import_redund() the part which checks
which Environment is valid into a separate function
called env_check_redund() and call it from env_import_redund().

So env_check_redund() can be used from places which also
need to do this checks.

Migrate from_env() from pxe.c to nvedit.c as it's not pxe specific.

Since commit af95f206 ("env: Create a new file for environment functions"),
a new header file exists.

So, this commit add a missing header file.

Fixes:

include/env.h:158:1: error: unknown type name ‘ulong’; did you mean ‘long’?
 ulong env_get_ulong(const char *name, int base, ulong default_val);

Add an ENV prefix to these two flags so that it is clear what they relate
to. Also move them to env.h since they are part of the public API. Use an
enum rather than a #define to tie them together.

These definitions are effectively part of the 'public' API of the
environment implementation since they do not require access to any
internal variables. Move them to the env.h header.

At present we have environment.h but this file includes all the
environment-related header files as well as internals such as
default_environment.

It seems desirable to have a new header to hold the commonly used
environment functions, so that most files can avoid including all of this
unnecessary stuff.

Create a new env.h header and move one function over to it.
