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.

bionic: change properties benchmarks to read a single property

The properties benchmarks were reading n properties from a property
area with n properties in it, which was making it hard to compare
the time between runs of different sizes.  Change the benchmark
to read a random property per iteration so the numbers between
runs are comparable.

11 years agolibc: add limited FORTIFY_SOURCE support for clang

libc: add limited FORTIFY_SOURCE support for clang

In 829c089f83ddee37203b52bcb294867a9ae7bdbc, we disabled all
FORTIFY_SOURCE support when compiling under clang. At the time,
we didn't have proper test cases, and couldn't easily create targeted
clang tests.

This change re-enables FORTIFY_SOURCE support under clang for a
limited set of functions, where we have explicit unittests available.
The functions are:

* memcpy
* memmove
* strcpy
* strncpy
* strcat
* strncat
* memset
* strlen (with modifications)
* strchr (with modifications)
* strrchr (with modifications)

It may be possible, in the future, to enable other functions. However,
I need to write unittests first.

For strlen, strchr, and strrchr, clang unconditionally calls the
fortified version of the relevant function. If it doesn't know the
size of the buffer it's dealing with, it passes in ((size_t) -1),
which is the largest possible size_t.

I added two new clang specific unittest files, primarily copied
from fortify?_test.cpp.

I've also rebuild the entire system with these changes, and didn't
observe any obvious problems.

11 years agolibc: Introduce __errordecl()

libc: Introduce __errordecl()

Define __errordecl and replace __attribute__((__error__("foo")))
with __errordecl. Make sure __errordecl is a no-op on clang, as it
generates a compile time warning.
