a71c56a clientversion: Use full commit hash for commit-based version descriptions (Luke Dashjr)
Pull request description:
git keeps changing the number of digits in abbreviated hashes, resulting in the GitHub archive hash changing because we include it here.
To workaround this and avoid hashes that become increasingly ambiguous later on, just include the full commit hash when building from git.
This has no effect on tagged releases.
(Cleanly mergable back to 0.10 without backport)

* The following part of the code determines the CLIENT_BUILD variable.
|
|
* Several mechanisms are used for this:
|
|
* * first, if HAVE_BUILD_INFO is defined, include build.h, a file that is
|
|
* generated by the build environment, possibly containing the output
|
|
* of git-describe in a macro called BUILD_DESC
|
|
* * secondly, if this is an exported version of the code, GIT_ARCHIVE will
|
|
* be defined (automatically using the export-subst git attribute), and
|
|
* GIT_COMMIT will contain the commit id.
|
|
* * then, three options exist for determining CLIENT_BUILD:
|
|
* * if BUILD_DESC is defined, use that literally (output of git-describe)
|
|
* * if not, but GIT_COMMIT is defined, use v[maj].[min].[rev].[build]-g[commit]
|
|
* * otherwise, use v[maj].[min].[rev].[build]-unk
|
|
* finally CLIENT_VERSION_SUFFIX is added
