* 'master' of github.com:/avikivity/osv:
  mkbootfs: remove errant print
  build: quiet down mkbootfs invocation
  scripts: support multiple objects in running image
  elf: store object list in an area easily accessible to the debugger
  printf: implement zero fill
  libc: import qsort from freebsd

 - add git submodule init
 - use the right flag for autoreconf

Since we're loading multiple objects, we need to load symbol tables for all
of them.  The base addresses are no longer static (esp. after we started
loading mulitple payloads, so we need to read them from the image).

A new command is added for this: 'osv syms'.  It will try to locate symbol
tables for anything that has been loaded at this stage.

Since we're loading many objects, we need to make them accessible to the
debugger so it can load symbol tables.

as in "%016lx".

Reserves a vma range for later use.  Can be useful to implement mmap() hints
with a two-step algorithm - reserve a range, then overwrite it with the real
mmap.

This is simpler than [addr, addr+size) for splitting and merging.

(gdb) osv heap

The ABI requires that the stack be aligned to 16 bytes, so sse can be used.
Make it so.  Fixes the jvm assembler faulting.

Add a variable for all possible payload files, and reactive the now fixed
quiet build.

Convert from libc mutex to osv mutex.

For some reason this didn't work.  Also make sure to clean out so
files in make clean so this gets noticed.

An off-by-one meant the the object pool for sizes above half a page was
not initialized.
