Allows us to compose an event message for our own in-memory purposes.
Will be used to compose an event message in logd and directly write
it to just the pmsg buffer. Provide an internal enhanced C++ wrapper
for event handling.

FileWriter::Create() calls ftruncate(2) to truncate the destination
file, which doesn't work with FD that references a block device. It
leads to kIoError when calling ExtractEntryToFile() to extract an entry
to block device FD.
As a result, it fails the package_extract_file() command in OTA updates
(e.g. 'package_extract_file("boot.img",
"/dev/block/platform/soc.0/f9824900.sdhci/by-name/boot")').
This CL skips the call to ftruncate(2) if FD references a block device.

Expand logprint feature to pull out the log tag description
fields, parse them and merge into the logging content. Add
-v descriptive, -v colour(british, hidden) and -v help. Also
added a unit test for the descriptive format borrowing from
event tags that have been unchanged since 2009.
Had to add -v help because we have too many undocumented
formats and format adverbs.

Solve one more issue where privilege is required to open a file and
we do not want to grant such to the service. This is the client side
of the picture, init is the server. The file's descriptor was placed
into the environment as "ANDROID_FILE_<path>" where non-alpha and
non-numeric characters in the <path> are replaced with _ and this
function picks the file descriptor up.
Added definition ANDROID_FILE_ENV_PREFIX ("ANDROID_FILE_") and
android_get_control_file() prototype in a new include <cutils/files.h>
android_get_control_file() checks if the resulting file descriptor is
valid, open and matches the name reference, which on purpose will fail
if a symbolic link is in the path rather than using a fully qualified
path. Add gTest unit test for both.

Native bridge implements namespace related interfaces in version 3.
The namespace semantic here is same as Android dynamic linker's.
Native loader wraps library loading functions of dynamic linker and
native bridge. Thus, Android runtime is able to load native library
of different ISA on one device by calling native loader directly.

We went too far, so this is a partial revert, part deux.
Keep general purpose logging macros in android/log.h for the NDK.
More internal features like Radio, System and Events logging are
moved back to log/log.h. Correct liblog ndk symbols. Correct for
some Android Coding standards.

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.

'system/core: drop or replace log/logger.h' and
'system/core: Replace log/log.h with android/log.h'.

Add private function __android_logger_get_buffer_size() to read
properties and compose the default buffer size. This interface
complements the existing android_looger_get_size() which returns
the logd setting which can differ at runtime. For use in logd
and dumpstate. Side effect is we also add the private functions
__android_logger_property_get_bool() and
__android_logger_valid_buffer_size() for reuse in logd.
Test: gTest liblog-unit-test, logd-unit-tests and logcat-unit-tests in
combination with commit 'logd: Use private interfaces for
buffer size properties'

HIDL requires file descriptors to be wrapped in native_handle_t. We want
a low overhead way to do that when the number of file descriptors is known
at compile time. Instead of
// wrap an fd in native_handle_t
native_handle_t* fd_handle = native_handle_create(1, 0);
if (!fd_handle) {
// clean up and return error
}
fd_handle->data[0] = fd;
hidl_cb(..., fd_handle);
native_handle_delete(fd_handle);
this change adds native_handle_init to allow for
// wrap an fd in native_handle_t
NATIVE_HANDLE_DECLARE_STORAGE(fd_storage, 1, 0);
native_handle_t* fd_handle = native_handle_init(fd_storage, 1, 0);
fd_handle->data[0] = fd;
hidl_cb(..., fd_handle);
