[oe] [meta-oe][PATCH v2] pcapplusplus: add new recipe
"A multiplatform C++ library for capturing, parsing and crafting of
network packets"
PcapPlusPlus is currently transitioning from a custom build system
(shell script + Makefile) to CMake. After this has been merged, SRC_URI
must be set the main repository.

RFC --> v2:
- Update patch status (Submitted --> Accepted)
- inherit dox2unix (files in GIT have Windows line endings)
- convert patch to unix line endings
v1 --> RFC:
- move to Clément Péron's fork [branch: cmake-ng]
- change recipe to cmake
- add patch for -Wnarrowing warnings/errors
- build shared libraries
- remove RDEPENDS:${PN}-dev (main pkg contains now shared libs)
- add -Wno-psabi to CXXFLAGS
This is the 2nd attempt to move the build system of PcapPlusPlus to
CMake. I highly suppose that this will get merged soon.

+Subject: [PATCH] Fix timeval-to-timespec conversions
+
+Time values returned by gettimeofday() have microseconds in
+timeval::tv_usec while timespec::ts_nsec is nanoseconds.
+
+timeval::tv_usec is 64 bit (at least on some platforms), while
+timespec::tv_nsec is always 'long'. An explicit cast is required to
+avoid -Wnarrowing warnings/errors.
+
+Upstream-Status: Accepted [https://github.com/seladb/PcapPlusPlus/pull/814]

We will soon convert to Unix EOL.
