go: include vendored modules

RHEL requires the source code for dependencies to be included in the
srpm. The spec file already expects that, but we've only included the
vendored modules (i.e., the `vendor` directory) in the `rhel-8.2.`
branch. Move vendoring to master, so that we can build RHEL packages
from it as well.

This commit is the result of running `go mod vendor`, which includes the
vendored sources and updates go.mod and go.sum files.

Fedora requires the opposite: dependencies should not be vendored. The
spec file already ignores the `vendor` directory by default.

+> Go Globbing Library.
+
+## Install
+
+```shell
+    go get github.com/gobwas/glob
+```
+
+## Example
+
+```go
+
+package main
+
+import "github.com/gobwas/glob"
+
+func main() {
+    var g glob.Glob
+    
+    // create simple glob
+    g = glob.MustCompile("*.github.com")
+    g.Match("api.github.com") // true
+    
+    // quote meta characters and then create simple glob 
+    g = glob.MustCompile(glob.QuoteMeta("*.github.com"))
+    g.Match("*.github.com") // true
+    
+    // create new glob with set of delimiters as ["."]
+    g = glob.MustCompile("api.*.com", '.')
+    g.Match("api.github.com") // true
+    g.Match("api.gi.hub.com") // false
+    
+    // create new glob with set of delimiters as ["."]
+    // but now with super wildcard
+    g = glob.MustCompile("api.**.com", '.')
+    g.Match("api.github.com") // true
+    g.Match("api.gi.hub.com") // true
+        
+    // create glob with single symbol wildcard
+    g = glob.MustCompile("?at")
+    g.Match("cat") // true
+    g.Match("fat") // true
+    g.Match("at") // false
+    
+    // create glob with single symbol wildcard and delimiters ['f']
+    g = glob.MustCompile("?at", 'f')
+    g.Match("cat") // true
+    g.Match("fat") // false
+    g.Match("at") // false 
+    
+    // create glob with character-list matchers 
+    g = glob.MustCompile("[abc]at")
+    g.Match("cat") // true
+    g.Match("bat") // true
+    g.Match("fat") // false
+    g.Match("at") // false
+    
+    // create glob with character-list matchers 
+    g = glob.MustCompile("[!abc]at")
+    g.Match("cat") // false
+    g.Match("bat") // false
+    g.Match("fat") // true
+    g.Match("at") // false 
+    
+    // create glob with character-range matchers 
+    g = glob.MustCompile("[a-c]at")
+    g.Match("cat") // true
+    g.Match("bat") // true
+    g.Match("fat") // false
+    g.Match("at") // false
+    
+    // create glob with character-range matchers 
+    g = glob.MustCompile("[!a-c]at")
+    g.Match("cat") // false
+    g.Match("bat") // false
+    g.Match("fat") // true
+    g.Match("at") // false 
+    
+    // create glob with pattern-alternatives list 
+    g = glob.MustCompile("{cat,bat,[fr]at}")
+    g.Match("cat") // true
+    g.Match("bat") // true
+    g.Match("fat") // true
+    g.Match("rat") // true
+    g.Match("at") // false 
+    g.Match("zat") // false 
+}

+
+## Performance
+
+This library is created for compile-once patterns. This means, that compilation could take time, but 
+strings matching is done faster, than in case when always parsing template.
+
+If you will not use compiled `glob.Glob` object, and do `g := glob.MustCompile(pattern); g.Match(...)` every time, then your code will be much more slower.
+
+Run `go test -bench=.` from source root to see the benchmarks:
+
+Pattern | Fixture | Match | Speed (ns/op)
+--------|---------|-------|--------------
+`[a-z][!a-x]*cat*[h][!b]*eyes*` | `my cat has very bright eyes` | `true` | 432
+`[a-z][!a-x]*cat*[h][!b]*eyes*` | `my dog has very bright eyes` | `false` | 199
+`https://*.google.*` | `https://account.google.com` | `true` | 96
+`https://*.google.*` | `https://google.com` | `false` | 66
+`{https://*.google.*,*yandex.*,*yahoo.*,*mail.ru}` | `http://yahoo.com` | `true` | 163
+`{https://*.google.*,*yandex.*,*yahoo.*,*mail.ru}` | `http://google.com` | `false` | 197
+`{https://*gobwas.com,http://exclude.gobwas.com}` | `https://safe.gobwas.com` | `true` | 22
+`{https://*gobwas.com,http://exclude.gobwas.com}` | `http://safe.gobwas.com` | `false` | 24
+`abc*` | `abcdef` | `true` | 8.15
+`abc*` | `af` | `false` | 5.68
+`*def` | `abcdef` | `true` | 8.84
+`*def` | `af` | `false` | 5.74
+`ab*ef` | `abcdef` | `true` | 15.2
+`ab*ef` | `af` | `false` | 10.4
+
+The same things with `regexp` package:
+
+Pattern | Fixture | Match | Speed (ns/op)
+--------|---------|-------|--------------
+`^[a-z][^a-x].*cat.*[h][^b].*eyes.*$` | `my cat has very bright eyes` | `true` | 2553
+`^[a-z][^a-x].*cat.*[h][^b].*eyes.*$` | `my dog has very bright eyes` | `false` | 1383
+`^https:\/\/.*\.google\..*$` | `https://account.google.com` | `true` | 1205
+`^https:\/\/.*\.google\..*$` | `https://google.com` | `false` | 767
+`^(https:\/\/.*\.google\..*|.*yandex\..*|.*yahoo\..*|.*mail\.ru)$` | `http://yahoo.com` | `true` | 1435
+`^(https:\/\/.*\.google\..*|.*yandex\..*|.*yahoo\..*|.*mail\.ru)$` | `http://google.com` | `false` | 1674
+`^(https:\/\/.*gobwas\.com|http://exclude.gobwas.com)$` | `https://safe.gobwas.com` | `true` | 1039
+`^(https:\/\/.*gobwas\.com|http://exclude.gobwas.com)$` | `http://safe.gobwas.com` | `false` | 272
+`^abc.*$` | `abcdef` | `true` | 237
+`^abc.*$` | `af` | `false` | 100
+`^.*def$` | `abcdef` | `true` | 464
+`^.*def$` | `af` | `false` | 265
+`^ab.*ef$` | `abcdef` | `true` | 375
+`^ab.*ef$` | `af` | `false` | 145

+## Syntax
+
+Syntax is inspired by [standard wildcards](http://tldp.org/LDP/GNU-Linux-Tools-Summary/html/x11655.htm),
+except that `**` is aka super-asterisk, that do not sensitive for separators.
