At present we have three states for the environment, numbered 0, 1 and 2.
Add an enum to record this to avoid open-coded values.

This function is the same as env_get_char_spec() apart from dropping the
brackets. Drop the brackets from env_get_char_spec() and use that instead
of env_get_char_memory().

This function does nothing but call env_get_char_spec(). Drop it and
adjust its only caller.

The check for gd->env_valid is used in both the 'if' and 'else' part of
env_get_char(). Move it into that function instead for simplicity. Drop
that code from the two leaf functions.

This function is not used anywhere other than env_get_char(). Move the

These functions are not used outside this file. Make them static and order
them to avoid forward declarations.

About a quarter of the files in common/ relate to the environment. It
seems better to put these into their own subdirectory and remove the
prefix.
