buildhistory: rename build-id to build-id.txt and add more info
* use .txt extension like other reports (e.g. image-info.txt) it's
also useful when looking at the file from web server which doesn't
have text/plain as default content-type
* include whole BUILDCFG_HEADER/BUILDCFG_FUNCS instead of just layer
info
* this makes it easier for distro to include more fields without the
need to modify buildhistory.bbclass
* currently it adds following fields:
Build Configuration:
BB_VERSION = "1.23.1"
BUILD_SYS = "x86_64-linux"
NATIVELSBSTRING = "Gentoo-2.2"
TARGET_SYS = "x86_64-oe-linux"
MACHINE = "qemux86-64"
DISTRO = "shr"
DISTRO_VERSION = "2013.07-next-
20140725"
TUNE_FEATURES = "m64 core2"
TARGET_FPU = ""
