David Srbecky 85b5fecec9 Check for data races when reading JIT/DEX entries.
Update the entries only when the list is modified by the runtime.

Check that the list wasn't concurrently modified when being read.

Martin Stjernholm 2677b802bf Remove dependency on libdexfile internal header.
Also remove some tests for implementation details in the libdexfile API that
are now covered by unit tests there (http://r.android.com/867370).

Christopher Ferris 9d5712c123 Implement support for linker rosegment option.
The rosegment linker option results in two maps containing the elf data
existing. One is an execute map where the code lives, and the other is the
read-only segment which contains the elf header information. If the file
backing a shared library in memory is not readable, then the new code
will attempt to find the read-only map that has the same name as the
current execute segment, and that is at offest zero in the file.

Add new unit tests for this functionality.

Add the missing MapInfoCreateMemoryTest.cpp to the list of tests.

Bug: 109657296

Test: Pass new unit tests.
Test: All unit libbacktrace/libunwindstack tests pass with rosegment enabled.

David Srbecky 02d0f7962d Create lookup table of DEX symbols.
Create fast lookup table instead of iterating every single time.
This will create the cache as methods are searched for.

Christopher Ferris 7747b60faa Load dex files from ART-specific data structure.
Fixes cdex which was recently changed to have shared data section,
which means the DEX PC cannot be used to find the right symbol,
as the bytecode is no longer within the dex file, and in-fact,
we might have to scan multiple dex files to find the method.
