++/* (From RFC1521 and draft-ietf-dnssec-secext-03.txt)
++ The following encoding technique is taken from RFC 1521 by Borenstein
++ and Freed. It is reproduced here in a slightly edited form for
++ convenience.
++
++ A 65-character subset of US-ASCII is used, enabling 6 bits to be
++ represented per printable character. (The extra 65th character, "=",
++ is used to signify a special processing function.)
++
++ The encoding process represents 24-bit groups of input bits as output
++ strings of 4 encoded characters. Proceeding from left to right, a
++ 24-bit input group is formed by concatenating 3 8-bit input groups.
++ These 24 bits are then treated as 4 concatenated 6-bit groups, each
++ of which is translated into a single digit in the base64 alphabet.
++
++ Each 6-bit group is used as an index into an array of 64 printable
++ characters. The character referenced by the index is placed in the
++ output string.
++
++ Table 1: The Base64 Alphabet
++
++ Value Encoding Value Encoding Value Encoding Value Encoding
++ 0 A 17 R 34 i 51 z
++ 1 B 18 S 35 j 52 0
++ 2 C 19 T 36 k 53 1
++ 3 D 20 U 37 l 54 2
++ 4 E 21 V 38 m 55 3
++ 5 F 22 W 39 n 56 4
++ 6 G 23 X 40 o 57 5
++ 7 H 24 Y 41 p 58 6
++ 8 I 25 Z 42 q 59 7
++ 9 J 26 a 43 r 60 8
++ 10 K 27 b 44 s 61 9
++ 11 L 28 c 45 t 62 +
++ 12 M 29 d 46 u 63 /
++ 13 N 30 e 47 v
++ 14 O 31 f 48 w (pad) =
++ 15 P 32 g 49 x
++ 16 Q 33 h 50 y
++
++ Special processing is performed if fewer than 24 bits are available
++ at the end of the data being encoded. A full encoding quantum is
++ always completed at the end of a quantity. When fewer than 24 input
++ bits are available in an input group, zero bits are added (on the
++ right) to form an integral number of 6-bit groups. Padding at the
++ end of the data is performed using the '=' character.
++
++ Since all base64 input is an integral number of octets, only the
++ -------------------------------------------------
++ following cases can arise:
++
++ (1) the final quantum of encoding input is an integral
++ multiple of 24 bits; here, the final unit of encoded
++ output will be an integral multiple of 4 characters
++ with no "=" padding,
++ (2) the final quantum of encoding input is exactly 8 bits;
++ here, the final unit of encoded output will be two
++ characters followed by two "=" padding characters, or
++ (3) the final quantum of encoding input is exactly 16 bits;
++ here, the final unit of encoded output will be three
++ characters followed by one "=" padding character.

++/* here's how these things work.
++
++ when adbd starts, it creates a unix server socket
++ named @vm-debug-control (@ is a shortcut for "first byte is zero"
++ to use the private namespace instead of the file system)
++
++ when a new JDWP daemon thread starts in a new VM process, it creates
++ a connection to @vm-debug-control to announce its availability.
++
++
++ JDWP thread @vm-debug-control
++ | |
++ |-------------------------------> |
++ | hello I'm in process <pid> |
++ | |
++ | |
++
++ the connection is kept alive. it will be closed automatically if
++ the JDWP process terminates (this allows adbd to detect dead
++ processes).
++
++ adbd thus maintains a list of "active" JDWP processes. it can send
++ its content to clients through the "device:debug-ports" service,
++ or even updates through the "device:track-debug-ports" service.
++
++ when a debugger wants to connect, it simply runs the command
++ equivalent to "adb forward tcp:<hostport> jdwp:<pid>"
++
++ "jdwp:<pid>" is a new forward destination format used to target
++ a given JDWP process on the device. when sutch a request arrives,
++ adbd does the following:
++
++ - first, it calls socketpair() to create a pair of equivalent
++ sockets.
++
++ - it attaches the first socket in the pair to a local socket
++ which is itself attached to the transport's remote socket:
++
++
++ - it sends the file descriptor of the second socket directly
++ to the JDWP process with the help of sendmsg()
++
++
++ JDWP thread @vm-debug-control
++ | |
++ | <----------------------|
++ | OK, try this file descriptor |
++ | |
++ | |
++
++ then, the JDWP thread uses this new socket descriptor as its
++ pass-through connection to the debugger (and receives the
++ JDWP-Handshake message, answers to it, etc...)
++
++ this gives the following graphics:
++ ____________________________________
++ | |
++ | ADB Server (host) |
++ | |
++ Debugger <---> LocalSocket <----> RemoteSocket |
++ | ^^ |
++ |___________________________||_______|
++ ||
++ Transport ||
++ (TCP for emulator - USB for device) ||
++ ||
++ ___________________________||_______
++ | || |
++ | ADBD (device) || |
++ | VV |
++ JDWP <======> LocalSocket <----> RemoteSocket |
++ | |
++ |____________________________________|
++
++ due to the way adb works, this doesn't need a special socket
++ type or fancy handling of socket termination if either the debugger
++ or the JDWP process closes the connection.
++
++ THIS IS THE SIMPLEST IMPLEMENTATION I COULD FIND, IF YOU HAPPEN
++ TO HAVE A BETTER IDEA, LET ME KNOW - Digit

++/* we implement socketpairs directly in use space for the following reasons:

++ * - it allows us to implement fdevent hooks easily and cheaply, something
++ * that is not possible with standard Win32 pipes !!
++ *
++ * basically, we use two circular buffers, each one corresponding to a given
++ * direction.
++ *
++ * each buffer is implemented as two regions:
++ *
++ * region A which is (a_start,a_end)
++ * region B which is (0, b_end) with b_end <= a_start
++ *
++ * an empty buffer has: a_start = a_end = b_end = 0
++ *
++ * a_start is the pointer where we start reading data
++ * a_end is the pointer where we start writing data, unless it is BUFFER_SIZE,
++ * then you start writing at b_end
++ *
++ * the buffer is full when b_end == a_start && a_end == BUFFER_SIZE
++ *
++ * there is room when b_end < a_start || a_end < BUFER_SIZE
++ *
++ * when reading, a_start is incremented, it a_start meets a_end, then

++ * and thus is sensitive to network disruptions. For instance, the
++ * ConnectionManager may decide to reset all network connections, in which case
++ * the connection between ADB host and guest will be lost. To make ADB traffic

++ * between the host, and the guest. See external/qemu/android/adb-*.* that
++ * implements the emulator's side of the protocol. Another advantage of using
++ * QEMUD approach is that ADB will be up much sooner, since it doesn't depend
++ * anymore on network being set up.
++ * The guest side of the protocol contains the following phases:
++ * - Connect with adb QEMUD service. In this phase a handle to 'adb' QEMUD service
++ * is opened, and it becomes clear whether or not emulator supports that
++ * protocol.
++ * - Wait for the ADB host to create connection with the guest. This is done by
++ * sending an 'accept' request to the adb QEMUD service, and waiting on
++ * response.
++ * - When new ADB host connection is accepted, the connection with adb QEMUD
++ * service is registered as the transport, and a 'start' request is sent to the
++ * adb QEMUD service, indicating that the guest is ready to receive messages.
++ * Note that the guest will ignore messages sent down from the emulator before
++ * the transport registration is completed. That's why we need to send the
