nvcuda sample: add comments about missing features in the BOINC CUDA sample code:
* Code to determine the correct device assigned by BOINC.
* Code to select which NVIDIA GPU to use if there are more than one.
Mac: update build of client from openssl-1.0.1c to openssl-1.0.1e
client: improved CPU type and feature detection.  From [P3D Crashtest]
client (win): fix typo in last commit
API (Android) sched_yield() before sleep() in signal handler

Trying to fix bug where timer thread stops doing anything
after first suspend on Android (old, 1-core devices).
I suspect that the sleep() in the worker thread's signal handle
is sleeping the entire process.
Insert a sched_yield() before the sleep so that the time thread will run.
admin web: add option to Cancel Jobs page to cancel only unsent jobs
Mac: documentation update
MGR: On Linux, initialize exclusive apps dialog to start from directory "/usr/bin/" instead of from "/" (from Toralf Förster)
WINBUILD: Re-enable the custom actions which modify the VirtualBox.VirtualBox permissions so that boinc_project can launch VMs.
client: initialize device_status_time (shouldn't make any difference)
web: show product name in host lists, and don't show domain name twice
API (Android): check whether the SIGALRM signal is erroneously being handled by the timer thread
Android GUI: fix a couple of strings
client: include project resource shares in account manager request message
MGR: fix permissions error string in stderrgui.txt
admin web: fix typo in cancel jobs page
client (Android): allow GUI to pass MAC address to client via set_host_info().  If domain name is "localhost" and MAC address is nonempty, use MAC address instead of domain name when showing host on project web page.
web: remove mobile venue for the time being
client (Android): don't use network preferences

Many Android users had existing preferences with settings like
"don't compute when idle" that make sense for PCs but not mobile devices.
When this pref is enforced on Android, no computing happens
and user confusion results.
We're addressing this by using only local prefs on Android.
We considered other approaches - e.g. having a "mobile" venue -
but they're too complex.
