Add methods to report host memory total, host memory available,
process memory available, host memory used, and process memory
used. In this context memory is unavailable if there are resource
limits in place that would prevent its use. Such resource limits
assumed to be applied on a per host basis both to cooperatively
operating process groups, such as mpi programms running in parallel,
and to individual processes. When reporting host memory available
consult an application specified environment variable. When reporting
process memory available consult unix resource rlimits and an
application specified environment variable. The environmant variables
provide a means of communicating resource limits that are being
applied in a non-standard way.

Fix interaction between local variables and conditional code in methods

 SystemInformationImplementation::GetFullyQualifiedDomainName
 SystemInformationImplementation::GetMemoryTotal
 SystemInformationImplementation::GetMemoryUsed
 SystemInformationImplementation::GetProcessId

to avoid assigning values to local variables that are never used.

While at it, fix GetMemoryUsed() to not leak the OpenProcess handle when
GetProcessMemoryInfo fails.

Support probing of the current process memory usage in KB
(linux,win,mac), the total physical memory in KB (linux,win,mac), and
the model name field of the cpuinfo (Linux only).  Add a method to
return the host's FQDN (non-AIX), and methods to test for OS type
(Windows, Apple, Linux).

Add a script implementing our standard "git gerrit-push" alias.  When
invoked, first check that the current branch is a named topic.  Then
fetch 'master' from the 'gerrit' remote repository so the local
repository can compute a minimal pack to push.  Finally, push the topic
to the 'gerrit' remote as "refs/for/master/$topic".

Commit "KWSys: Fix SystemTools environment memory handling" (2012-04-26)
added a _WIN32 case inside !KWSYS_CXX_HAS_ENVIRON_IN_STDLIB_H to dllimport
the "environ" global.  Howver, KWSYS_CXX_HAS_ENVIRON_IN_STDLIB_H is true
on every Windows toolchain we support so the case is never reached.
Furthermore, even if it were reached the use of dllimport is incorrect
because the toolchain might not be compiling with a dynamic runtime
library.  Remove the unused incorrect line and supporting conditionals.

Add a .gitattributes line to match both "config.sample" and any config
file added by the containing project.

Configure a separate pushurl only if it is different from the main url.

Honor the $username placeholder in the 'gerrit.url' configuration value.
Configure a separate pushurl only if it is different from the main url.

The hash_fun.hxx header is configured whether FundamentalType is enabled
or not and so cannot depend on it.  Run the relevant platform tests
whether or not FundamentalType is on and configure the result directly
into hash_fun.  While at it, remove the dependence of SystemInformation
on FundamentalType too since it needs only information that we now
always compute.

When the topic stage has already been configured present the current
configuration and prompt for optional reconfiguration.  While at it,
make the topic stage remote name configurable by the project.

The SystemTools::PutEnv function tries to provide the "putenv" API
without leaking memory.  However, the kwsysDeletingCharVector singleton
frees memory that may still be referenced by the environment table,
having been placed there by putenv.  If any static destruction or
processing by an external tool happens after the singleton is destroyed
and accesses the environment it will read invalid memory.

Replace use of putenv with setenv/unsetenv when available.  The latter
manage internal copies of the values passed instead of referencing the
original memory.  When setenv/unsetenv are not available use putenv with
a singleton that removes its values from the environment before freeing
their memory.  This requires an "unputenv" implementation.  On at least
some platforms it must be written in terms of "putenv" because other
APIs are not available and direct modification of the "environ" global
is not safe (e.g. on Windows there is interaction with "wenviron").
Fortunately either putenv("A=") or putenv("A") will remove "A" from the
environment on these platforms.  On other platforms fall back to direct
manipulation of "environ".

Also add UnPutEnv to the API and add a test for the behavior of both.

KWSys is no longer shared in projects via a server-side directory
symlink in CVS.  An automated nightly date stamp commit can no longer be
shared by multiple projects directly.  It needs a per-project replay
robot so the nightly commits end up needing N+1 robots instead of N.
Remove the DateStamp feature because it is no longer useful or
maintained by nightly commits.

Add the "export-ignore" attribute to all such files.  Remove the
suggestion from the README since this should not be a responsibility
of the including project.

Interactively prompt the user for ~/.ssh/config setup.

Interactively prompt the user with Gerrit setup instructions.

Fetch the hooks right out of the local clone if possible.  Otherwise
fall back to a project-configured remote repository.

Prompt the user to configure user.name and user.email interactively.

Fix a crash which occurs when SystemTools::GetPath attempts to process
an empty environment variable.
