Use fixed length types for structs going over the wire, constify
arguments where possible, use char* instead of unsigned char* for
apacket data, and assorted other refactoring.

Test: python test_device.py with every combination of old/new adb and adbd
Change-Id: I0b6f818a32be5386985aa4519f542003cf427f9d
All of the functions in adb_auth.cpp were used in only one of
adb/adbd. Split up them up into adb_auth_host.cpp and adbd_auth.cpp
respectively.

CHUNK_HEADER structure type allows DATA chunk to be up to MAX_UINT
large.
The write() callback LEN parameter should be unsigned int.
Also:
- write() callback should continue to write data if less than expected
data have been written.
- gzerror() returns LEN on success, 0 otherwise

On 64 bit system, calculates to roughly 80 bytes of metadata and
list overhead for each entry.
In unit test example, we report 3388987 bytes of logging data and
overhead total, showmap reports 4652K of dirty data. We still want
to account for the remainder (fragmentation, other sources of
internal allocations etc).
Test: see values and check math

Undo zero-termination-substitution for linebreaks when logging.
This results in handing the complete log message to the aborter.
Add a test.

debuggerd does not require log/logger.h, can use android/log.h
In some cases, mark why log/logger.h was required.

Allows us to mitigate the impact of MAP_PRIVATE and copy on write by
calling android_lookupEventTag_len instead of android_lookupEventTag,
and delaying the copy on write impact to the later. We return a
string length in a supplied location along with the string pointer
with android_lookupEventTag_len(const EventTagMap* map, size_t* len,
int tag). The string is not guaranteed to be nul terminated. Since
android_lookupEventTag() called even once can cause the memory
impact, we will mark it as deprecated, but we currently have no
timeframe for removal since this is a very old interface.
Add an API for __android_log_is_loggable_len() that accepts the non
null terminated content and fixup callers that would gain because the
length is known prior to the call either in the compiler or at
runtime. Tackle transition to android_lookupEventTag_len() and
fixup callers.

Added liblog-unit-tests --gtest_filter=liblog.event_log_tags to
check for Shared_Clean: to not be 0 and Anonymous: to be 0 for
all processes referencing event-log-tags. Which can include multiple
references to /system/etc/event-log-tags and future possible refs to
/data/misc/logd/event-log-tags and /dev/event-log-tags. We want
failure messages to help point to errant code using the deprecated
interface.
This change saves 1/4MB of memory or more on a typical system.

These events are _somewhat_ normal, in that not all devices have all
partitions, but not logging anything makes it unnecessarily hard for
folks to debug simple failures.
