574780b002 pkg/csource: prevent unused-result warnings 
Warnings for write unused-result fire on travis,
somehow I don't get them locally.

b9f93868ed dashboard/app: use CCYY/MM/DD hh:mm format 
Since dateSort does not take years into account, Time field of long-standing
bugs is not sorted correctly. Also, it will become more useful to
include year of closed date after we operate the dashboard for some years.
Thus, this patch changes the format of formatTime method, and use textSort
for sorting.

Based on patch by Tetsuo Handa.

b7d8ccf74f executor: include more headers on fuchsia 
Since we are taking address of functions in syscall table,
we need all headers even if we don't use them directly.

bdc18a387e Makefile: format C sources before generating Go 
If executor common headers are unformatted then go generate pkg/csource
will embed unformatted headers. Then format_cpp will re-format
only executor headers, but not embed versions. As the result
pkg/csource will end up with wrong embed headers.

Format C sources before generating Go to fix this.

4cd4cbd625 Makefile: don't use target go to build build binaries 
Build of host Go binaries is broken on fuchsia,
because we use target toolchain and it creates broken binaries.
Introduce HOSTGO and use it for host binaries.

57799a834f prog: fix and improve fallback coverage 
First we emitted fallbackSignalFlags inside of the loop,
while we need to this outside of the loop.
Second, make flags signal weaker otherwise we get all 256
signals for open, chmod, etc.
Third, simplify and speedup code.

Currently we first send on errs and then close env.
As the result process can exit before env.Close finishes,
which will leave garbage behind.
