linker didn't remove link to the soinfo from shared
namespaces on soinfo_unload, because it didn't keep
record of all namespaces the library is added to.
This change adds test for this and also fixes the
problem by introducing list of secondary namespaces
to soinfo, which is used to remove soinfo in
soinfo::remove_all_links().

linker doesn't call d-tors for RTLD_NODELETE libraries. There is
no need in reseting this flag in call_destructors (which is called
from soinfo_unload).

Linker was not unloading libraries marked with RTLD_NODELETE
even when there was a error on load. For example when one of
dt_needed libraries was not found.

Add missing test for sleb128_decoder. Also remove
dependency to static library because it exposes malloc/free
which interfere with libc.so malloc/free causing test to crash.

Handle no longer is a pointer to soinfo of

This patch uses __kernel_vsyscall instead of "int 0x80"
as the syscall entry point. AT_SYSINFO points to
an adapter to mask the arch specific difference and gives a
performance boost on i386 architecture.

This reverts commit 0acb15ead6.
This workaround is not needed any more. Now ART generates
.MIPS.abiflags segments in its files. This is done in
Ie06a3c4e384a23a77db7d04a2508edbf3a6d3933.

The previous code assumed that returning would be sufficient to rethrow
signals like SIGSEGV. This is not true, for example, in the case where a
SIGSEGV is sent via kill(2). We were previously only sending the signal
to ourselves in some cases, because using kill(2) would lose information
in the siginfo_t argument. Use rt_tgsigqueueinfo(2) instead to preserve
its contents.

This field is used only once and only for main executable;
no need to carry it around in soinfo structure.

Small modifications needed to allow compilation with the new headers:
- Manually modify bionic/libc/kernel/uapi/asm-mips/asm/siginfo.h to
remove the uapi from the include.
- PR_XXX defines are now available for mips, so remove the definition
from linker_mips.cpp.

Look into "/system/lib" before "/vendor/lib", this way
we can ensure that in case of name conflict /system libraries
take precedence.

dlclose used to unmap the part of the reserved region
for ANDROID_DLEXT_RESERVED_ADDRESS that was neccessary
to map PT_LOAD segments. With this change dlclose
replaces mapped PT_LOAD segments with a PROT_NONE,
MAP_ANONYMOUS | MAP_NORESERVE.
Previously caller was unmapping the reserved region after
the failed dlclose which led to race condition when someone
else reused the region freed by dlclose but before the unmap
by the chromium code.

Exactly which functions get a stack protector is up to the compiler, so
let's separate the code that sets up the environment stack protection
requires and explicitly build it with -fno-stack-protector.

Shared namespaces clone the list of loaded native
libraries from the caller namespace. This allows
classloaders for bundled apps to share already loaded

The anonymous namespace is introduced to
handle cases when linker can not find the
caller. This usually happens when caller
code was not loaded by dynamic linker;
for example mono-generated code.
