Continue using the legacy NDK android/log.h.
system/core/android/log.h needs some work before it can be included in
the NDK. It defines a *lot* of macros that previously were usable
names in NDK sources that used android/log.h. As an example, the
following file defines LOG_TAG as a variable, but the variable name
gets macro replaced if we use the current android/log.h.
4adc1515f8/framework/platform/android/tcuTestLogParserJNI.cpp (41)
For now, we keep a copy of the old NDK android/log.h in
legacy-ndk-includes.
Test: make checkbuild

*
|

* This file is part of Android's set of stable system headers

*
|

* Third-party source AND binary code relies on the definitions

|

*
|

* - DO NOT MODIFY ENUMS (EXCEPT IF YOU ADD NEW 32-BIT VALUES)
|
||||

|

/*
|
||||
* Support routines to send messages to the Android in-kernel log buffer,
|
||||
* which can later be accessed through the 'logcat' utility.
|
||||
*
|
||||
* Each log message must have
|
||||
* - a priority
|
||||
* - a log tag
|
||||
* - some text
|
||||
*
|
||||
* The tag normally corresponds to the component that emits the log message,
|
||||
* and should be reasonably small.
|
||||
*
|
||||
* Log message text may be truncated to less than an implementation-specific
|
||||
* limit (e.g. 1023 characters max).
|
||||
*
|
||||
* Note that a newline character ("\n") will be appended automatically to your
|
||||
* log message, if not already there. It is not possible to send several messages
|
||||
* and have them appear on a single line in logcat.
|
||||
*
|
||||
* PLEASE USE LOGS WITH MODERATION:
|
||||
*
|
||||
* - Sending log messages eats CPU and slow down your application and the
|
||||
* system.
|
||||
*
|
||||
* - The circular log buffer is pretty small (<64KB), sending many messages
|
||||
* might push off other important log messages from the rest of the system.
|
||||
*
|
||||
* - In release builds, only send log messages to account for exceptional
|
||||
* conditions.
|
||||
*
|
||||
* NOTE: These functions MUST be implemented by /system/lib/liblog.so
