Remove /data/dalvik-cache/profiles from domain. Profiling information
leaks data about how people interact with apps, so we don't want
the data to be available in all SELinux domains.

Add read/write capabilities back to app domains, since apps need to
read/write profiling data.

Remove restorecon specific rules. The directory is now created by
init, not installd, so installd doesn't need to set the label.

Originally we used the shell domain for ADB shell only and
the init_shell domain for the console service, both transitioned
via automatic domain transitions on sh.  So they originally
shared a common set of rules.  Then init_shell started to be used
for sh commands invoked by init.<board>.rc files, and we switched
the console service to just use the shell domain via seclabel entry
in init.rc.  Even most of the sh command instances in init.<board>.rc
files have been converted to use explicit seclabel options with
more specific domains (one lingering use is touch_fw_update service
in init.grouper.rc).  The primary purpose of init_shell at this point
is just to shed certain permissions from the init domain when init invokes
a shell command.  And init_shell and shell are quite different in
their permission requirements since the former is used now for
uid-0 processes spawned by init whereas the latter is used for
uid-shell processes spawned by adb or init.

Given these differences, drop the shelldomain attribute and take those
rules directly into shell.te.  init_shell was an unconfined_domain(),
so it loses nothing from this change.  Also switch init_shell to
permissive_or_unconfined() so that we can see its actual denials
in the future in userdebug/eng builds.

write_logd() is allowed for domain, which means that all domains
are permitted read/write access to /dev. That's overly permissive
and causes substantial differences between user and userdebug/eng
devices.

Remove domain device:dir rw_dir_perms access. It's not needed.

Allow all domains to write/append to logd_debug. logd is responsible
for creating this file if need be. Remove logd_debug file create
permissions. This also eliminates the need for the type_transition
rules.
