Fix adb forward --list when forwarding a lot

The list action had some problems with large numbers of forwards:
 * adb_query() limited replies to 1024 B (and the print was useless)
 * the reply header's length could overflow (also in other commands)
 * ...and the client had no way of detecting it
 * writex() didn't retry on EAGAIN ("Resource temporarily unavailable")

This patch makes all "OKAY%04x" replies use a common function which
checks the length and limits it to 0xffff. This means that the client
can easily check for truncated replies.

Before: forward --list starts failing at 15-30 forwards (depending on
device serial and forward spec lengths).

After: no problems with forward --list.

Fix the handling of CodeCache return codes in pixelflinger

The error condition was not correctly detected: an error was
reported by checking that the index returned by CodeCache::cache
was non-zero. This did not work because this function can return
a positive value on success.

uid_from_user doesn't need to cope with numeric ids in the BSD code

Also explain what SUPPORT_DOT is for.

Use the getopt function in compliance with the standard.

This is a simple change to the use of getopt in reboot.c, as per the standard,
getopt does NOT return an EOF, it returns a -1, (this was done to remove
getopt's dependence on stdio.h), and since the standard does not guarantee 
that EOF is -1, and the documentation tells us that getopt returns -1, 
in my judgement it would be best to test for -1, rather than EOF.
