Change lookup order during relocation so that
ld_preloads always precede caller (unless caller
is main executable).
Asan needs this change in order to intercept libc->libc
calls.

When enabling debug malloc, the snprintf calls in the linker fails to
update the buffer.
The problem is that snprintf makes a call to pthread_getspecific that
returns a valid pointer, but the data it points to is zero. This should
never happen and causes the snprintf to stop and do nothing.
Temporarily replace snprintf with a different implementation to work
around this issue.

This includes:
1. Placing has_ifunc after fields with version = 0
2. Switch to has_min_version(v) function.
3. Minor soinfo initialization refactoring (placement new + ctor)

Do not run symbol lookup on already visited soinfos
Not taking into account already visited libraries
dramatically slows down dlsym in cases when there
are multiple occurrences of a large library in
dependency tree.

/system/bin/tf_daemon on Nakasi has been updated so it's
a PIE executable. We can now drop non-PIE support.
This reverts commit d81b3b275dff99561cbe5905ca63a1c72fa54a17.

On Nakasi builds, /system/bin/tf_daemon is a pre-compiled
vendor supplied binary. When support for non-PIE executables
was removed, that daemon failed to start, which induced
a number of bugs.
* keystore is broken
* CTS runs will hang after a certain period of time
Temporarily reenable non-PIE support for 32-bit platforms
until Nakasi is fixed.
This rolls back the following commits:
Cleanup: updated comments
* 6275f2083415d22a6ce0de55645079cd47e0cc80
Cleanup: remove AARCH/ARM_COPY relocation support
* b906e13c55c9fe9b4157ba548534a0230434882b
And restricts the following patch to 64 bit only:
Remove support for non-PIE executables

While introducing RTLD_NOLOAD in b648a8a5 a change in how soinfo structs are
connected was also introduced. When calling dlopen the library that is loaded
is added as a child to the soinfo from which the caller comes - i.e. building a
dependency graph.
Unfortunately this shows issues upon unloading, such as blowing the stack if
there are loops in the graph.
This change reverts that part of b648a8a5, keeping everything as a child of the
root soinfo.

Linker is now able to resolve symlinked libraries correctly.
soinfo is extended to save the graph of dependencies during
load/unload. Dependencies are used only in CallConstructor.
