06cffd468f power: refactor ACPI and intel_pstate support
Currently, ACPI and PSTATE modes have lots of code duplication,
confusing logic, and a bunch of other issues that can, and have, led to
various bugs and resource leaks.

This commit factors out the common parts of sysfs reading/writing for
ACPI and PSTATE drivers.

02a6d68311 power: fix namespace for internal struct
Currently, ACPI code uses rte_power_info as the struct name, which
gives the appearance that this is an externally visible API. Fix to
use internal namespace.

7f15f0fbed power: save original ACPI governor always
Currently, when we set the acpi governor to "userspace", we check if
it is already set to this value, and if it is, we skip setting it.

However, we never save this value anywhere, so that next time we come
back and request the governor to be set to its original value, the
original value is empty.

Fix it by saving the original pstate governor first. While we're at it,
replace `strlcpy` with `rte_strscpy`.

99a2dd955f lib: remove librte_ prefix from directory names
There is no reason for the DPDK libraries to all have 'librte_' prefix on
the directory names. This prefix makes the directory names longer and also
makes it awkward to add features referring to individual libraries in the
build - should the lib names be specified with or without the prefix.
Therefore, we can just remove the library prefix and use the library's
unique name as the directory name, i.e. 'eal' rather than 'librte_eal'
