source index for git repo.
The current windbg source index suite doesn't support git repo. here one solution is given by DOS script.

- 
Syntax: 
 gitIndex.cmd <sourceCodeDir> <pdbFilesDirPath>
- 
example 
 gitIndex.cmd "d:\myProject\newFeature" "d:\myProject\newFeature\output\bin"
 gitIndex.cmd will make source index for all pdb files under path "d:\myProject\newFeature\output\bin" and update those pdb files.
- 
you can refer to the example in the path: 
 https://github.com/shenxiaolong-code/sourceIndex_forGit/blob/master/test/test_pdbDirAll.bat
- 
config windbg tool path 
 if your windbg tool "srctool.exe" is added to %path%, you needn't do anything , else you need to update the file "userLocalPathConfig.bat"
 below is my windbg x86 path setting:
 where pdbstr.exe 2>nul || @set "path=C:\Program Files (x86)\Windows Kits\10\Debuggers\x86\srcsrv;%path%"
 where windbg.exe 2>nul || @set "path=C:\Program Files (x86)\Windows Kits\10\Debuggers\x86;%path%"
- 
you need to prepare one local git repo 
 it is used to fetch a single repo file with a specified commit id. (fetched file doesn't overwrite this repo file, see "gitFetchFile.cmd" for detail.)
 e.g. assume your git repo path is "D:\sourceCode\jabberGit129" , you need to set environment varialbe :
 setx localGitRepo "D:\sourceCode\jabberGit129"
 this variable is used in "gitFetchFile.cmd" , certain you can edit "gitFetchFile.cmd" directly without puting it into system environments.
- 
add gitFetchFile.cmd to system search path. 
 you need to put gitFetchFile.cmd path in %path%, or copy it into system directory (e.g. C:\windows\system32).
 the debugger will seek to download a specified file with a specified commit ID. (that info comes from source index)
