Title: Microkernel Object Performance

Description:
Eliminate VxMicro branding in sample projects Eliminates references to the obsolete OS name. In most cases the name is simply removed, as it isn't necessary. Change-Id: I3796f2aebe802f8c6045b7424a3e7aab4d5fb8e8 Signed-off-by: Allan Stephens <allan.stephens@windriver.com>

AppKernel is used to measure the performance of microkernel events, mutexes,
semaphores, FIFOs, mailboxes, pipes, memory maps, and memory pools.

Revise misleading instructions in sample project README.txt files Removes the instruction directing users to issue "make pristine" before building a sample project, as this should be unnecessary under normal circumstances and can cause the user to unexpectedly lose their current configuration information. In its place, a section on troubleshooting is added that describes how to rebuild a project using the desired configuration.

Troubleshooting:
Problems caused by out-dated project information can be addressed by
issuing one of the following commands then rebuilding the project:
make clean # discard results of previous builds
# but keep existing configuration info
or
make pristine # discard results of previous builds
# and restore pre-defined configuration info
