2014-01-14common, env: optimize boottimeHeiko Schocher
when creating the hashtable, for each environmentvariable getenv(ENV_CALLBACK_VAR) and getenv(ENV_FLAGS_VAR) is called, which costs at this point a lot of time. So call this two getenv() calls only once.

2012-12-13env: Add a command to display details about env flagsJoe Hershberger
Similar to the env callback command, this will show details about the options available, the static list, and the currently active variables. Signed-off-by: Joe Hershberger <joe.hershberger@ni.com>
2012-12-13tools/env: Add environment variable flags supportJoe Hershberger
Currently just validates variable types as decimal, hexidecimal, boolean, ip address, and mac address. Call env_acl_validate_setenv_params() from setenv() in fw_env.c. If the entry is not found in the env .flags, then look in the static one. This allows the env to override the static definitions, but prevents the need to have every definition in the environment distracting you. Need to build in _ctype for isdigit for Linux.
