Fix build badge (#135) 
The badge referred to the outdated release (which has been deleted for a while now). This PR updates it so that the master is used.

e88c1f4518 Sort the input file list (#133) 
so that libsqlparser.so.1 builds in a reproducible way
in spite of indeterministic filesystem readdir order.

See https://reproducible-builds.org/ for why this is good.

9701403ff5 Fix multi-threaded parsing (#110) 
This should fix multi-threaded parsing. Not a clean solution, I am guessing the following block should be a single, state-less pattern? @mrks

```
\'                          { BEGIN singlequotedstring; strbuf = std::stringstream{}; }
<singlequotedstring>\'\'    { strbuf << '\''; }
<singlequotedstring>[^']*   { strbuf << yytext; }
<singlequotedstring>\'      { BEGIN 0; yylval->sval = strdup(strbuf.str().c_str()); return SQL_STRING; }
<singlequotedstring><<EOF>> { fprintf(stderr, "[SQL-Lexer-Error] Unterminated string\n"); return 0; }
```

Anyway, the following hyrise playground does not crash anymore, so Toni should be able to work with this for the time being.

```c++
#include <iostream>
#include <thread>

#include "types.hpp"
#include "tpch/tpch_queries.hpp"
#include "SQLParser.h"

using namespace opossum;  // NOLINT

int main() {
  std::vector<std::thread> threads;

  for (size_t t = 0; t < 200; ++t) {
    threads.emplace_back([&]() {
      for (size_t p = 0; p < 10'000; ++p) {
        hsql::SQLParserResult result;
        hsql::SQLParser::parse(tpch_queries.at(19), &result);
        std::cout << "Parsing " << p << " is valid: " << result.isValid() << std::endl;
      }
    });
  }

  for (auto& thread : threads) {
    thread.join();
  }

  return 0;
}
```

cdd271490b Allow more variations of LIMIT/OFFSET 
In addtion to already supported LIMIT/OFFSET variants allow more to be parsed

Legacy:
  - LIMIT int
  - LIMIT int OFFSET int

Enhancement:
  - OFFSET int             (no limit)
  - LIMIT ALL              (no limit)
  - LIMIT NULL             (no limit)
  - LIMIT ALL OFFSET int   (no limit, but offset)
  - LIMIT NULL OFFSET int  (no limit, but offset)

Also ensures negative limits / offsets are set to kNoLimit/kNoOffset

66688f7199 Adjust Table Join Types 
Consolidate LeftOuter/Left and RightOuter/Right as they are
by definition the same.
Similar consolidate FullOuter/Outer/Full ... with Outer (as in the
parser) not part of standard, but "full" missing. Allowing all three.

This commit potentially breaks other programs as kJoinLeftOuter and kJoinRightOuter
are eliminated

66804a6281 Allow '==' to be parsed as equal operator in expressions. 
SQLite allows for this and it is in the same spirit as allowing both != and <>
for non equality.
