Christopher Faylor da086d020c * cygheap.cc (cygheap_user::set_name): Set homedrive and homepath to NULL on
user name change.
(cygheap_user::set_logsrv): Allocate enough space for leading \\ so that we can
put this in the environment, if needed.
* cygheap.h (homebodies): New enum.
(cygheap_user::homedrive): New field.
(cygheap_user::homepath): Ditto.
(cygheap_user::env_logsrv): New method.
(cygheap_user::env_homepath): New method.
(cygheap_user::env_homedrive): New method.
(cygheap_user::env_userprofile): New method.
(cygheap_user::ontherange): New method.
* environ.cc (envsize): Eliminate debugging argument.
(environ_init): Assume that envc counts number of elments not total size.
(spenv): New class.
(spenvs): New array, renamed from forced_winenv_vars, using spenv.
(spenv::retrieve): New method.
(build_env): Rename from 'winenv' -- one stop shopping for building new
environment blocks for both windows and "unix".
* environ.h (build_env: Declare.
(winenv): Delete declaration.
(envsize): Ditto.
* spawn.cc (spawn_guts): Use build_env to build windows and cygwin environment
blocks.
* uinfo.cc (internal_getlogin): Eliminate environment manipulation.  Default to
info from GetUserName if it exists.  Move HOMEPATH and HOMEDRIVE stuff
elsewhere.  Move HOME setting elsewhere.  Only set HOME environment variable in
processes that are not parented by a cygwin process.
(cygheap_user::ontherange): Define new method.
(cygheap_user::env_logsrv): Ditto.
(cygheap_user::env_homepath): Ditto.
(cygheap_user::env_homedrive): Ditto.
(cygheap_user::env_userprofile): Ditto.
