Update libgit2 to 0.27

Hello everyone,

0.27.x is released long time ago, but I never got time for updating it. It
obviously involves SONAME change.

The good thing about this release is that it breaks only things in runtime
and only one function changed signature (for building) which nobody uses

I'm going to update library as soon as I get time (possibly on this weekend
if no all dependent packages build fine). I will handle all rebuilds
myself, just sending a notice.

List of affected packages is below.

R-git2r qulogic

Hi Igor,

Thanks for your work. Just noticed that julia hasn't been built
succesfully (<a href="" title=""></a>)
. Seems to have failed with: "cc1plus: error: unrecognized command line
option '-mcet'"

This is currently an issue in Fedora Scientific building. What would be the
path forward here?

Drop '-mcet'? It's a bit hard to find docs for it, but [1] says:
"""-mcet -fcf-protection enables support for the Control-Flow

generation of additional NOPs, which are ignored by the current
CPUs. It is recommended that you enable this flag now, to detect any
issues caused by them (e.g., interactions with dynamic
instrumentation frameworks, or performance issues)."""

It sounds like it's not something that is particularly needed at this

The build log also has a lot of:
/usr/include/features.h:381:4: warning: #warning _FORTIFY_SOURCE requires compiling with optimization (-O) [-Wcpp]
# warning _FORTIFY_SOURCE requires compiling with optimization (-O)
This sounds like the package is not being built with the distro flags.

<a href="" title=""></a> seems to suggest
that this was implemented explicitly?

I am way out of touch, but a quick search for `mcet` in the package SRPM
and the source tarball from (<a href="" title=""></a>),
didn't show up `mcet` being explicitly added either.

A lot of the scientific stacks appear to do as they please here (they
might have an exception, I'm not sure), but they have a tendency to
use very x86 specific ones, in most cases if they used the distro ones
the code would actually build/run across mult arch platforms. After
getting yelled at for trying to fix it I moved on with life.
