07440a8773 Replace TLS_SLOT_BIONIC_PREINIT w/ shared globals 
Instead of passing the address of a KernelArgumentBlock to libc.so for
initialization, use __loader_shared_globals() to initialize globals.

Most of the work happened in the previous CLs. This CL switches a few
KernelArgumentBlock::getauxval calls to [__bionic_]getauxval and stops
routing the KernelArgumentBlock address through the libc init functions.

Bug: none
Test: bionic unit tests

c11fb66739 Inline __libc_arc4random_has_unlimited_entropy. 
The name is misleading anyway.

585fc3e554 Add __libc_arc4random_unlimited_entropy. 
Let the caller know when libc has an entropy source and arc4random is safe.
This is useful for the callers that want entropy, but don't absolutely need it.

78a52f19bb Attempt to use arc4random where getauxval(AT_RANDOM) is used. 
When arc4random can get entropy (which is true for basically everyone
but init on kernels that don't support getrandom), use it instead of
AT_RANDOM.
