c9084427aa linker: Emit a warning on text relocations 
Text relocations unnecessarily mark pages as dirty, preventing them
from being swapped out, wasting memory. Also, text relocations
prevent the code from running on certain hardened systems.

Print a message in logcat and stderr when we see a text relocation,
to encourage developers to fix their code.

17fc25d20f libc_logging: don't keep file descriptors open forever 
Avoid keeping unnecessary file descriptors around when they're not
needed. Libc doesn't log so much that opening / closing overhead
matters.

5bfa3ee8b3 bionic: add missing memory barriers to system properties 
1) Reading the value must finish before checking whether it's intact

2) Setting the serial's dirty bit must visible before modifying the
value

3) The modified value must be visible before clearing the serial's dirty
bit

4) New properties and their TOC entries must be visible before updating
the property count

d32969701b bionic: make property area expandable 
The property area is initially one 4K region, automatically expanding as
needed up to 64 regions.

To avoid duplicating code, __system_property_area_init() now allocates
and initializes the first region (previously it was allocated in init's
init_property_area() and initialized in bionic).  For testing purposes,
__system_property_set_filename() may be used to override the file used
to map in regions.

c6ff844d75 bionic: add __system_property_foreach 
find_nth() will be inefficient on a trie.  Since find_nth() is only used
internally and only for enumerating properties, we can add a foreach()
function to do this directly.

7e5a8cc523 Make LD_PRELOAD failures just warnings. 
This matches glibc and makes life easier for developers who want to
sometimes preload a library from init (which has no conditionals); they
can simply move/remove the library to disable.
