ueventd: load modules in a forked process

Loading some modules (e.g., ath3k) will be blocked to wait for
firmware. The forking is necessary, otherwise ueventd has no
chance to load the firmware.

libutils: fix incorrect calculation in utf8_length() method

The first character of utf-8 could be larger than 128. If use signed char
variable to hold it, it would be treated as negative. That may result in
some unexpected errors.

For example, without this patch, suppose the code is 0xE88888, then
first_char is 0xE8 and converted to int32_t type (0xFFFFFFE8) and
masked with (~to_ignore_mask). The result utf32 is FFF08208
which is incorrect.

init.rc: use relative path for symlink

Usually it's better to use relative path for symlink. For example,
to use Android in a chroot environment, the absolute symlink will
fail outside the chroot environment. Using relative path guarantees
the link will work both inside and outside chroot.

LibNativeBridge: Version 2

Add a callback function to retrieve "signal handler" from the bridge,
if the bridge wants it to be managed by the runtime. The signal handler
will be invoked after the runtime's own one, and before any other
chained handler.

Add a callback function to check compatibility of the bridge with the
library.

Add a function to expose the native bridge version. Add a test for this
function.

logd: Fix pruning

In a scenario in which an on-line (blocking) client is running and
a clean is attempted (logcat -c), the following can be observed:

1) the on-line logger seems to freeze
2) any other clear attempt will have no effect

What is actually happening:

In this case prune function will "instruct" the oldest timeEntry
to skip a huge number (very close to ULONG_MAX) of messages, this
being the cause of 1.

Since the consumer thread will skip all the log entries, mStart
updating will also be skipped. So a new cleaning attempt will have
the same oldest entry, nothing will be done.

Fix description:
a. keep a separated skipAhead count for individual log buffers (log_id_t)
LogTimeEntry::LogTimeEntry
LogTimeEntry::FilterSecondPass
LogTimeEntry::skipAhead
LogTimeEntry::riggerSkip_Locked

b. update LogTimeEntry::mStart even if the current message is skipped
LogTimeEntry::FilterSecondPass

c. while pruning, only take into account the LogTimeEntrys that are monitoring
the log_id in question, and provide a public method of checking this.
LogTimeEntry::isWatching
LogTimeEntry::FilterFirstPass
LogTimeEntry::FilterSecondPass

d. Reset the skip cont befor the client thtread starts to sleep, at this point
we should be up to date.
LogTimeEntry::cleanSkip_Locked
LogTimeEntry::threadStart

System/core: Use memmove

Should use memmove when you expect overlap.

Change-Id: I268a173db40a4be54232958e37aa8a03c2a885ee

When new error happend, then errno should be updated accordingly. Otherwise, need to keep previous errno.

Reproduced steps:
pre-condition:
DUT support external SDcard or Usb mass storage;

1. Insert blank(no partition) SDcard or UMS to DUT;

Expected result:
Should prompt user with storage error.

Test result:
There is no notification for error.

Error log:
01-01 01:06:49.239 I/fsck_msdos( 200): fsck_msdos terminated by exit(8)
01-01 01:06:49.239 E/Vold ( 200): /dev/block/vold/179:16 failed FS checks (I/O error)
01-01 01:06:49.239 D/Vold ( 200): Volume sdcard1 state changing 3 (Checking) -> 1 (Idle-Unmounted)
01-01 01:06:49.239 W/Vold ( 200): Returning OperationFailed - no handler for errno 0)

Root cause analysis:
1.Volume::setState will call senBroadcase to send out state notification;
2.Finally, SocketClient::sendDataLockedv was called to sent message.
In sendDataLockedv funtion, when current == iovcnt, e is 0 by default.
So Vold get incorrect errno.

UPSTREAM_PENDING newfs_msdos: Handle alignment failure

When trying to create a new FAT32 file system using alignment, the resulted
MBR structure is corrupted, because the total sectors reported does not
correspond to the actual available sectors. This is due to the reserved
sectors field which is updated during the alignment.

When fsck_msdos will try to check this file system, it will fail because it
cannot match the reported sectors with the actual available sectors.
Due to the failed check, the file system cannot be mounted by vold.

I/fsck_msdos( 2180): FAT size too small, 242822 entries won't fit into 1897 sectors
I/fsck_msdos( 2180): fsck_msdos terminated by exit(8)
E/Vold ( 2180): Filesystem check failed (unknown exit code 8)
E/Vold ( 2180): /dev/block/vold/179:49 failed FS checks (I/O error)
D/Vold ( 2180): Volume sdcard1 state changing 3 (Checking) -> 1 (Idle-Unmounted)

In order to fix this issue, we will save the initial bpb structure and restore
it if the alignment fails.

devices: Increase the uevent socket buffer size

Depending on the timing, hald may start while ueventd is not done yet
with its initial coldboot. As hald also independently starts its own
coldboot, ueventd netlink socket buffer could get filled quickly and
thus ueventd could lose some uevents.
This is fixed by increasing the ueventd netlink socket buffer size.

RefBase: make Renamer destructor virtual

This patch makes the Renamer class destructor virtual and fixes
the incorrect constructor initialization list ordering.

These issues and related compiler warnings have been suppressed
by the build system which uses the gcc –isystem command
line option, unless a project explicitly adds the include the path
system/core/include to Android.mk and uses the templates.
