Hi

Here are some improvements for using kcore (version 6).  There are 3
improvements:

	- validate that kcore matches the perf.data modules
	- workaround objdump difficulties with kcore
	- add kcore to the build-id cache

Changes in V6:
	perf tools: make a separate function to parse /proc/modules
		Dropped because it has been applied
	perf tools: workaround objdump difficulties with kcore
		Renamed some functions and reordered parameters
	perf buildid-cache: add ability to add kcore to the cache
		Renamed some functions and reordered parameters

Changes in V5:
	perf tools: make a separate function to parse /proc/modules
		Use scnprintf not snprintf
	perf tools: validate kcore module addresses
		Fix check for mi->name not allocated
	perf buildid-cache: add ability to add kcore to the cache
		Use scnprintf not snprintf
	perf tools: add ability to find kcore in build-id cache
		Use scnprintf not snprintf

Changes in V4:
	perf tools: fix path unpopulated in machine__create_modules()
		Dropped because it has been applied
	perf buildid-cache: add ability to add kcore to the cache
		Tweaked Documentation/perf-buildid-cache.txt
	perf tools: add ability to find kcore in build-id cache
		Changed to check read access to /proc/kcore before
		skipping the buildid cache

Changes in V3:
	perf tools: workaround objdump difficulties with kcore
		change strncpy to strlcpy
	perf buildid-cache: add ability to add kcore to the cache
		change strncpy to strlcpy
	perf tools: add ability to find kcore in build-id cache
		change strncpy to strlcpy
Changes in V2:
	perf tools: fix buildid cache handling of kallsyms with kcore
		Dropped because it has been applied
	perf tools: fix path unpopulated in machine__create_modules()
		Use 'modules' pointer
