d2962c8a15 Remove dead code.
If this was strlcpy16 it wouldn't be such a bad idea, but strncpy16 is
just an accident waiting to happen...

bf3fff1a9e libutils: Fix bug in strstr16.
In the original code when target is an empty string
strlen16() would start reading the memory until a
"terminating null" (that is, zero) character is found.
This may happen because "*target++", at line 300,
would increment the pointer beyond the actual string.

47efc676c8 Fix integer overflow in utf{16,32}_to_utf8_length
Without an explicit check, the return value can wrap around and return
a value that is far too small to hold the data from the resulting
conversion.

No CTS test is provided because it would need to allocate at least
SSIZE_MAX / 2 bytes of UTF-16 data, which is unreasonable on 64-bit
devices.

Test: run cts -p android.security

cfd5b080af system/core: preparation to pull back interfaces from android/log.h
Point to log/log.h where necessary, define LOG_TAG where necessary.
Accept that private/android_logger.h is suitable replacement for
log/logger.h and android/log.h.

Correct liblog/README

Effectively a cleanup and controlled select revert of
'system/core: drop or replace log/logger.h' and
'system/core: Replace log/log.h with android/log.h'.

Should use android/log.h instead of log/log.h as a good example
to all others.  Adjust header order to comply with Android Coding

1cfa56d46c libutils/Unicode.cpp: Correct length computation and add checks for utf16->utf8
Inconsistent behaviour between utf16_to_utf8 and utf16_to_utf8_length

0fd60eb9b4 Fix strstr16.
strcmp needs a limit, otherwise it will compare the null terminator
with the next character in the haystack, which results in the compare
failing for all searches except where the needle is found at the very
end.

72299bf0d2 [Bug]NE when playing mp3 with incorrect UTF16 char
Bug: 15274351
Bug: 15539240

Many MP3 files have incorrect utf16 chars, but the
Utf16_to_utf8_length() routine checks for errors in
standard utf16 char.  utf16_to_utf8() was not checking
for errors in standard utf16 char.
