Roland McGrath	aae707cd88	[lsan] Expose Frontier object to OS-specific LockStuffAndStopTheWorld callback This is a small refactoring to prepare for porting LSan to Fuchsia. On Fuchsia, the system supplies a unified API for suspending threads and enumerating roots from OS-specific places like thread state and global data ranges. So its LockStuffAndStopTheWorld implementation will make specific callbacks for all the OS-specific root collection work before making the common callback that includes the actual leak-checking logic.

[lsan] Expose Frontier object to OS-specific LockStuffAndStopTheWorld callback

This is a small refactoring to prepare for porting LSan to Fuchsia.
On Fuchsia, the system supplies a unified API for suspending threads and
enumerating roots from OS-specific places like thread state and global data
ranges. So its LockStuffAndStopTheWorld implementation will make specific
callbacks for all the OS-specific root collection work before making the
common callback that includes the actual leak-checking logic.

[lsan] Fix deadlock in dl_iterate_phdr.

Summary:
Do not grab the allocator lock before calling dl_iterate_phdr. This may
cause a lock order inversion with (valid) user code that uses malloc
inside a dl_iterate_phdr callback.
