Hi Simon, Tom,

env_get_char() is a relic from the past when env was read char-by-char
from underlying device. Currently it only accesses in-memory arrays.
We can remove it and access the arrays directly. This simplifies the old
code of env_get_f().

Changes since v1:
- use memcpy() instead of strncpy() when copying value to buffer
- fixed a bug in patch adding check to terminating NULL-byte
- added patch fixing documentation for env_get_f()
- added patch changing behaviour of return value of env_get_f()
- some other cosmetic changes

Marek Behún (13):
  env: Fix documentation for env_get_f()
  env: Drop env_get_char_spec() and old, unused .get_char()
    implementations
  examples: api: glue: Remove comment that does not apply anymore
  env: Change env_match() to static and remove from header
  env: Don't match empty variable name in env_match()
  env: Check for terminating null-byte in env_match()
  env: Inline env_get_char() into it's only user
  env: Early return from env_get_f() on NULL name
  env: Use string pointer instead of indexes in env_get_f()
  env: Use better name for variable in env_get_f()
  env: Make return value of env_get_f() behave like sprintf() on success
  env: Use memcpy() instead of ad-hoc code to copy variable value
  env: Move non-cmd specific env functions to env/common.c
