Bug: 227282691
Change-Id: I498c62853562a8fc6702bdd622603b6f7d516274
This CL added additional tests for converting between utf16 and utf8,
specifically tests that:
1. check utf16_to_utf8_length() returns 0 if input is an
empty UTF16 string
2. check utf16_to_utf8_length() returns 1 if input is a
single ASCII character UTF16 string
3. check utf16_to_utf8_length() returns 3 if input is a
single UTF-16 character between U+0800 - U+FFFF
4. check utf16_to_utf8_length() returns 4 if input has
a surrogate pair
5. check unpaired UTF-16 surrogate is handled correctly
(skipped)
6. check utf16_to_utf8_length(0 handles invalid surrogate
case correctly, by skipping the first but handling the
rest correctly
7. check a normal string with a mix of 1/2/3/4-byte UTF8
characters is correctly converted by utf16_to_utf8()
8. check conversion from invalid utf8 sequence with invalid
leading byte and/or invalid trailing byte(s) should still
work and not crash

This includes memory header for shared_ptr and unique_ptr templates.
Fixes the following errors:
RefBase.h:803:1: error: ‘shared_ptr’ does not name a type
RefBase.h:810:1: error: ‘unique_ptr’ does not name a type

Done here:
- path saved to a useable location on host
- path always printed (for visibility for new users)
- open(.., 666) - That's '01204' not '0644' oops
Future considerations:
- make defines constexpr instead of ifdef
- copy malloc hook design to avoid needing to recompile code
- make libutilscallstack default on host
- run libutils tests, not just test compile debug mode
- code incorrectly prints ref 'doesn't exist'
seems it's gotten out of sync, but still good enough
to use stacktraces

I've seen these fixed before, so we compile the debug modes
now.

Unify all our "noinline" variants to the current most common one, not
least because the new [[noinline]] syntax is fussier about where it goes.

The CallStack unwind of a different thread was broken since it
wasn't properly setting the tid value.
Fix this problem and add new unit tests to verify the behavior.
Bug: 246405269
Test: New unit tests pass.
Test: Ran unit tests for 1000 operations to verify not flaky.

The function objects work equally well without them, and the base
classes were wrong for both types:
* HashForEntry: returns size_t but declared to return hash_t
(uint32_t)
* EqualityForHashedEntries: returns bool and takes two parameters but
declared to return hash_t and take one parameter
std::unary_function was deprecated in C++11 and removed in C++17.
Upstream libc++ now removes the type for new-enough C++ dialects.

make sure it worked.

Before, we only did this in sp<> constructors, but we can always make
this check during the initial incStrong.
Since prebuilts call into the existing report race function declared
in StrongPointer.h, we still call this function from RefBase.cpp.

The diff_flags make the ABI checker ignore the weak symbol difference
caused by PGO.
Ignore-AOSP-First: This patch relaxes the ABI check for T only.

Replaces libbacktrace in CallStack. There is one small behavioral
change, the BuildId data is added to the unwinds.

Test: All unit tests pass.

Let's turn a bug into a feature... Since this code is built with intsan,
anyone who caused overflow here will have had an abort, so we know
no-one actually needs the BAD_INDEX return that was presumably the
original author's intent. So let's just mandate that, since it's a lot
harder to ignore an abort than it is to ignore an error return.

Mark this as 29 for easy inclusion in APEXes when debugging. Make
sure we don't introduce calls to things here which would prevent
this from being used on old platforms.
