grep: Update to 3.5

[jannick0]

• grep/PKGBUILD:
  • update version and hash
  • remove references to outdated and obsolete patches
  • build binary in separate directory
• grep/{grep-2.23-msys2.patch,grep-3.0-2.patch}: remove files

Are those patches in upstream repository? If yes then a commit message with that upstream commit link would be helpful.

It not possible to update grep for MSYS2 as upstream drop support for crlf. So I hope it will not be merged

here is commit:

@Alexpux I fully agree that grep is a central piece to MSYS2. Yesterday I was not aware of this severe issue.

• The documentation (changed in the commit you are pointing to - thanks) does not read very clear to me (highlilghts from me):

Under MS-Windows, use binary I/O when reading and writing files other
than the user's terminal, so that all input bytes are read and written
as-is. This overrides the default behavior where @command{grep}
follows the operating system's advice whether to use binary or text
I/O.

• grep-3.0-2.src.patch cannot be reverted in the source of grep-3.5, since the target source file is removed meanwhile. So the much feared change does not show up in the source anymore.
• I am confused about grep's expected vs actual CRLF/LF handling now: What should grep do and what shouldn't it do (test cases?) with respect to -U, CRLF/LF in shell MSYS2/MINGW64/MINGW32,..., which input to grep?

Or am I missing something here?

@jannick0 look at #1353
