Treat "persist.sys.timezone" as being a Java-format timezone.

POSIX and Java disagree about the sign in a timezone string like "GMT+3".
This means that if you set "persist.sys.timezone" to such a string, native
code and Java code disagree about what time it is. Resolve this by
translating to POSIX form for native code.

Align-up and randomize shared libraries.

This change implements the following property:
  Any 2**N aligned memory region on size 2**N contains no more than one DSO.

The value N can be configured, with 16 or 18 looking like a good choice.
Additionally, DSOs are loaded at random page-aligned address inside these large
regions.

This change has dual purpose:
1. Larger values of N allow a lot more compact CFI shadow implementation.
   See change I14dfea630de468eb5620e7f55f92b1397ba06217.
   For example, CFI shadow for the system_server process has the following size (RSS, KB):
   152 for N = 12, 32 for N = 16, 16 for N = 18.
2. Extra randomization is good for security.

This change does not result in extra RAM usage, because everything is still page-aligned.
It does result in a bit more VM fragmentation because of the gaps between shared libraries.
As it turns out, this fragmentation is barely noticeable because the kernel creates new mapping
at the highest possible address, and we do enough small mappings to almost completely fill the
gaps (ex. in the Zygote the gaps are filled with .ttf file mappings and thread stacks).

I've measured VM fragmentation as the sum of all VM gaps (unmapped regions) that are larger
than 1MB according to /proc/$PID/maps. On aosp_angler-userdebug, the numbers are (in GB):

                |   N = 12  |  N = 18
system_server   |   521.9   |  521.1
zygote64        |   522.1   |  521.3

Defer registration of the arc4random fork-detect handler.

Previously, arc4random would register a fork-detecting pthread_atfork
handler to not have to call getpid() after a fork. pthread_atfork uses
pthread_mutex_lock, which requires the current thread to be initialized,
preventing the use of arc4random for initializing the global stack guard,
which needs to happen before the main thread has been initialized.

Extract the arc4random fork-detection flag and use the existing
arc4random fork handler to set it.
