[00/15] Build fixes for musl libc

  A set of patches to fix build with musl libc. I also did a few cleanups wrt
macros and fixed a few scary compiler warnings while at it.

Please note that those are only compile tested on x86_64 with musl libc.

Natanael Copa (15):
  app/testpmd: replace uint with unsigned int
  net/cxgbe: replace uint with unsigned int
  bus/pci: add fallback for out[lwb]_p for non GNU libc
  bus/pci: factor out various ifdefs in pci_uio_ioport_{read,write}
  bus/fslmc: fix compile error with musl libc
  bus/fslmc: remove unused include of error.h
  net/nfp: build fix for musl libc
  app/test: include fcntl.h due to use of O_RDONLY
  app/test: fix setting of -D_GNU_SOURCE with meson
  bus/dpaa: use warn(3) instead of error(3) to improve portability
  bus/dpaa: fix warning: "__WORDSIZE" is not defined, evaluates to 0
  crypto/dpaa2_sec: build fix for musl libc
  crypto/dpaa2_sec: simplify pr_{debug,err,warn} macros
  net/netvsc: fix compile warning for fcntl.h include
  eal/linux: use gettid(2) for debug message in sigbus_handler

I'm trying on Alpine Linux to build using make with the patches, and 
there are quite a few errors saying argp.h doesn't exist.

argp is a GNU extension and in Alpine we have it as a separate addon
package. Try `apk add argp-standalone`.

I also had to unset the RTE_BACKTRACE when building with ninja.
