Adds collection FILES_TMP_CONTENT

The collection is filled with a key-value set where value is the content of
the file which was uploaded. This collection can be used with all supported
operators, however, SecTmpSaveUploadedFiles should be set to 'On' in order
to have this collection filled. Note that @inspectFile is now depending on
SecTmpSaveUploadedFiles. This is necessary to keep performance while such
functionalities where not used.
Adds ssdeep support in our build system

ssdeep will be used with the @fuzzyHash operator which is under
development
Adds fuzzyHash operator

The fuzzyHash operator can be used to match files. In conjuntcion
with FILES_TMP_CONTENT collection it can scan uploaded files and
try to match it with a pre caculated list of know malicious content,
more details on how it works can be found on ssdeep website:
http://ssdeep.sourceforge.net/
iis: Adds ssdeep support
Adds regression test to cover the @fuzzeHash operator

Added 30-fuzzyHash.t and the ssdeep hash files. Hash files was generated using
files from ModSecurity repository.
FuzzyHash: if disable giving an run time error instead of config

FuzzyHash operator is optional and only installed if the headers for libfuzzy
was found in the system. Otherwise, the FuzzyHash operator is disable during
the compilation. After this commit, if some rules tries to use it, ModSecurity
will produce an runtime error not a config time error, allowing the web server
to procede normal with its operations.
Declares msre_var *rvar at the beggining of the function

Necessary to fix the build on Win8 VS 2011
Temporarily disable a test that is leading nginx buildbot to fail.
Adds automake subdir-objects option

As of Automake 1.4, it starts to warning about the lack of utilization
of `subdir-objects' option, which will be default in the further
releases. Avoiding break stuff we are patching ModSecurity to support
such option when it still an option (Issue #760).
Automake: Using ../ instead of $(top_srcdir)

After enable `subdir-objects', the variable $(top_srcdir) was not being
resolved, a directory labeled "$(top_srcdir)" was created instead.
Adds doxygen configuration files
Include apr-util's LDFLAGS

Using apr-util installed by Macports results in build failure because apr-util uses BerkeleyDB that MacPorts installs into a subdir of $prefix/lib and $prefix/include (so that multiple versions of BerkeleyDB can be installed simultaneously). apu-1-config's --ldflags output includes the -L/path/to/bdb that's needed.
mlogc: Changes the default SSL algo to TLS 1.2

As reported by Josh Amishav-Zlatin, mlogc was making usage of SSLv3 instead of
TLS 1.2. Servers should not answer SSLv3 after poodle.
mlogc: Checks if curl supports CURL_SSLVERSION_TLSv1_2 before use it

Seems like curl versions older than 7.34.0 does not have support for
`CURL_SSLVERSION_TLSv1_2'. In this cases, using CURL_SSLVERSION_TLSv1
which was added at version 7.9.2. ModSecurity demands a curl version
newer than 7.15.1.
Adds Status test case with the SecServerSignature being used

If SecServerSignature is used ModSecurity should send the real data, not the
one informed to SecServerSignature.
Originally reported by: Linas
Trims long `apache version' in the status call

As reported at #714 status calls with long `apache version' name was broken.
DNS queries cannot be so long. This field is now limited to 25 characters
which is a valid size when encoded into base32
Using real server signature on status call

On Apache platform the server signature can be replaced using the
SecServerSignature directive. Status call was using the signature informed by
this directive instead of using the original one. As reported at #702.
Adds curl support to main core

Curl was used only by mlogc, as we want to expand ModSecurity to load
external rules/resources it is now a dependency of the core as well.
Adds support to load remote resources to pmFromFile and ipMatchFromFile

Initially those directives were only able to load content from a
local file. This commit extends this functionality allowing the user to
provide an HTTP URI that can be downloaded and loaded by ModSecurity.
Initially the download is associated with a server restart. For next
versions we expect to load such resources as it become outdated (Without
need to resetart the server).
Initial support to load rules from a remote server

New directive `SecRemoteRules' was added. It allows the user to load a
set of rules from a given HTTP server.
