531f7cdb7a Blackbox: provide more space for log messages when reading from the blackbox. 
This is to allow for the header (16bytes and variable length function).
so if someone has a function name > 400 chars it will break. I
recon that will do:)

32abe38ffd avoid unwarranted use of strncpy: use memcpy instead 
* lib/log_format.c (qb_vsnprintf_deserialize): We know that there are
len or more non-NUL bytes in the source string, so it's clearer to
use memcpy.

a4411105a7 Correctly display timestamp in blackbox 
On little endian architectures where time_t is 64-bit long integer could
happen, that instead of displaying correct timestamp, random data was
used, because of memcpy.

Solution is to memcpy to real 32-bit variable and then assing this value
to timestamp. This will let compiler decide endianity and store number
correctly.

a notification of something in shared mem is available
in this case we really want to make sure we recv all
the notifications. So I have split these into 2 functions.

d823a480dc Fix a compile warning on sparc (epoll_create1) 
The problem is that sys/epoll.h was broken on sparc and alpha for a
bunch of glibc releases.

glibc has the symbol correctly exported, that's why ./configure finds
it, but the header is not always correct. Recent versions of glibc have
the correct header, so we simply workaround the broken ones.

This fix is only necessary to build with --enable-fatal-warnings,
otherwise you simply see a build warning, but there are no runtime
issues at any stage.

Angus Salkeld
683296f180 Fix ringbuffer creation on sparc 
On the first call to qb_rb_open() we try using a number of
page sizes. This because the system might have CONFIG_HUGETLB_PAGE_SIZE
defined in their kernel. So even though sysconf() returns 2K or 4K
some arch's mmap() require alignment on these boundaries.

these logs will not make there way to /var/log/messags

So to help on the fly debugging do the following:
qb_log_ctl(QB_LOG_SYSLOG, QB_LOG_CONF_PRIORITY_BUMP,

Now all messages that have the QB_LOG_SYSLOG target set
will have their priority bumped before going to syslog().

34c96d57e5 LOG: deal better with timestamps 
1) use gettimeofday() - suprisingly faster than clock_gettime(MONOTONIC)
2) don't format the time until it is needed
3) insert time_t into the blackbox (not a formatted string)

This improves performance and tidies the code up.
It also requires less space in the blackbox.
