or --license as most apps would do, instead it waits for data to
compress on stdin. Because of that, if `bzip2 --version' is called,
bogus `bzip2: I won't write compressed data to a terminal' error
message will be displayed, and checking for bzip2 version in scripts
as in
bzip2 --version 2>&1 | grep -o "Version [^,]*"

this by exiting right after showing version/license text.

Add recv callback to transport layer to better facilitate code reuse and
readability and for symmetry with send callback. Move recv_dgram and
recv_stream to udp_recv and lsock_recv, respectively, and make the
beforementioned functions recv callbacks for the udp and lsock transports,
respectively.
Consolidate the check_priv* functions in their relevant trans*.c source to

Note: this code is roughly based content from the submitter, although this
was modified to be more of a direct move from snmpd/main.c to the trans_*.c
sources, and to reduce unnecessary static function declarations.

The libgcc __register_frame and __deregister_frame functions take a
pointer to a set of FDE/CIEs, terminated by an entry where length is 0.
In Apple's libunwind implementation the pointer is taken to be to a
single FDE. I suspect this was just an Apple bug, compensated by Apple-
specific code in LLVM.
See lib/ExecutionEngine/RuntimeDyld/RTDyldMemoryManager.cpp and
http://lists.llvm.org/pipermail/llvm-dev/2013-April/061737.html
for more detail.
This change is based on the LLVM RTDyldMemoryManager.cpp. It should
later be changed to be alignment-safe.

executing :mincore_resid
The default process limits in FreeBSD is 64kB for unprivileged users,
which empirically is too low to run the :mincore_resid testcase.
Process limits are inherited, so even though the default limit for
root users is RLIM_INFINITY, the inherited limit with "sudo" with the
default login.conf will be 64kB.
Use setrlimit to set rlim_max for RLIMIT_MEMLOCK to RLIM_INFINITY to
avoid ENOMEM issues when calling mlock to wire the mmap'ed address
space.
setrlimit requires root access to increase rlim_max, so require root
privileges when running the test

Add some shortcuts in LazyValueInfo to reduce compile time of
Correlated Value Propagation.
The patch is to partially fix PR10584. Correlated Value Propagation
queries LVI to check non-null for pointer params of each callsite. If
we know the def of param is an alloca instruction, we know it is
non-null and can return early from LVI. Similarly, CVP queries LVI to
check whether pointer for each mem access is constant. If the def of
the pointer is an alloca instruction, we know it is not a constant
pointer. These shortcuts can reduce the cost of CVP significantly.
