[dpdk-dev] [PATCH v2 00/11] Include resources in tests

Hello,

another round. The code now looks better. Brief introduction:

This patch set introduces a mechanism to include a resource (in general a blob)
into the test binary. This allows to make tests less dependent on the target
testing environment. The first use case is testing of PCI bus scan by changing
the hard-coded path (/sys/bus/pci/devices) to something different and provide
a fake tree of devices with the test.

(CC: B. Richardson (accidently avoided in v1).)
---
v1:
* included 5 patches improving the PCI tests
* fixed using of non-existing RTE_INIT macro

v2:
* Makefile macro resource renamed to linked_resource
* introduced macro linked_tar_resource
* added more comments
* clarified relation between REGISTER_LINKED_RESOURCE and the Makefile
* untar is checked to not loop infinitely
* improved commit messages
* objcopy params extracted to a separated patcha (missing tile and ppc)
* few random bits (usually suggested by T. Monjalon)
* included a note about the new dependency libarchive in the particular commit
