0d787c1fa1 Make abort messages available to debuggerd.
This adds __libc_fatal, cleans up the internal logging code a bit more,
and switches suitable callers over to __libc_fatal. In addition to logging,
__libc_fatal stashes the message somewhere that the debuggerd signal handler
can find it before calling abort.

In the debuggerd signal handler, we pass this address to debuggerd so that
it can come back with ptrace to read the message and present it to the user.

c16961b8c3 system_properties: do more checking of file
Check that the permissions on the properties file
are exactly as we expect them to be.

Make sure we close the fd if fstat fails.

Refactor the code slightly.

32417fb376 libc: use more secure system properties if available
Currently, system properties are passed via the environment
variable ANDROID_PROPERTY_WORKSPACE and a file descriptor passed
from parent to child. This is insecure for setuid executables,
as the environment variable can be changed by the caller.

Modify system property handling so that we get the properties
from a root owned properties file, rather than using an
environment variable.  Fall back to the environment variable
if the file doesn't exist.

c20d0f3993 Correction to use of TEMP_FAILURE_RETRY in send_prop_msg
RETRY macro may retry command if result is -1. In this
case the command was "connect < 0" instead of just
connect. The comparison will not return -1 and thus
retry is never done. This is now corrected so that
interrupts will cause retry instead of fail.

(There was no other negative side effect of the bug.
The result code from RETRY was used in an if-statement
and it would be true for all negative connect results.
This was according to expectations.)

ec7e8cc9dd do not merge. Move property setting from libcutils to bionic.
Backport I110b653a58f3

All the other property stuff is already here.  Property setting was
only in libcutils previously to leverage a utility function / constant
or two.

Unfortunately in the process of fixing a race condition we would've
had to do break abstraction boundaries and put some libc-internal
details into libcutils so instead of that we'll just move this
into bionic.

Along with Iee1ca9b7, this now passes:

$ adb shell am instrument -w -e class android.os.SystemPropertiesTest \
  com.android.frameworks.coretests.systemproperties/android.test.InstrumentationTestRunner
