799512388c Revert the many un-reviewed commits starting from early April
Starting early April, a number of commits were pushed to the mob branch
that did not reflect the interest, wishes, or code quality of the tcc
community. This commit reverts those commits, while cherry-picking
grishka's commit for win64 linkage issues.

6e0a658e96 win64: try to fix linkage
- revert to R_X86_64_PC32 for near calls on PE
- revert to s1->section_align set to zero by default

Untested. Compared to release_0_9_26 the pe-image looks back to
normal.  There are some differences in dissassembly (r10/r11 usage)
but maybe that's ok.

This reverts commit 7a3f6d4941.

7a3f6d4941 Win: Enable use "*.def + *.c" files as library instead of *.a by "-l" option
example: "-lshell32" will try "shell32.def + shell32.c"

Add lib type "%s/%s.c" for tcc_add_library() ('-l' option parse)

So tcc can use all files as scripts.

     struct st st1;

     tcc a problem. Due to problems in front, and now can not be improved

504d40a328 Attention: never use hard tabs other than 8 (eight) wide
The attached fix (libcrt.c) is just one example.  There seem
many more such introduced from latest commits that look badly
formatted in anyone else's editors and should be fixed.

General recommended policy:
- if possible, do not add new hard tabs ('\t') at all.
  Use spaces (soft tabs) instead
- in any case, configure your editor to read/write hard tabs
  with width of 8 (eight)

Also:
- Avoid merge commits (unless for very good reason).  Instead
  use "git cherry-pick" or "git rebase" to put your commits on
  top of the public branch.  ref: 2a8905c93b

Also:
- jiang: please explain what you are doing, in the commit message
  and on the list. Subscribe to the mailing list to receive feedback
  from people for your work.

  For example, what was wrong with 'parse_number'? Show a test
  case and how your version fixes it (it is slower btw).
