Fixes for LLVM 4.0 and python3
Avoid conflicting [no]inline attributes in function annotation. This was
probably always there but now 4.0 is treating this as an error.
Also, explicitly inline several functions in helpers.h.
Turn off unwind tables in the flags passed to clang. This was generating
calls to the elf relocator, which doesn't work for the BPF target. It is
unclear which change in LLVM 4.0 altered this behavior.
On python3, handle byte strings in the usual way for supporting
backwards compatibility.

number of method calls and optionally their latency. This
is similar to `funccount` and `funclatency` but for methods
in Java, Python, Ruby, and other languages that might have
USDT probes for method entry and exit.
`ucalls` uses the `method__entry` and `method__return`
probes in Java and Ruby, and the `function__entry` and
`function__return` probes in Python. The Python probes are
not as accurate because they do not report the class name,
but are still useful.
The optional `-L` switch indicates whether latency numbers
are required. By default, only the number of calls to each
method is printed. The `-T` switch filters out the top
methods (by number of calls or total latency).
