Problem: Cannot handle binary data.
Solution: Add the Blob type. (Yasuhiro Matsumoto, closesvim/vim#3638)
6e5ea8d2a9
Nvim-specific Blob conversions are implemented in future commits.
Refactor write_blob() to use a FileDescriptor, as f_writefile() was
refactored to use one (does not apply to read_blob()).
Use var_check_lock() in f_add() for Blobs from v8.1.0897.
Add a modeline to test_blob.vim and fix some doc typos.
Include if_perl.txt's VIM::Blob() documentation. Interestingly, this
function already worked before this port, as it just returns a Blob
string literal, not an actual Blob object.
N/A patches for version.c:
vim-patch:8.1.0741: viminfo with Blob is not tested
Problem: Viminfo with Blob is not tested.
Solution: Extend the viminfo test. Fix reading a blob. Fixed storing a
special variable value.

vim-patch:8.1.1022: may use NULL pointer when out of memory
Problem: May use NULL pointer when out of memory. (Coverity)
Solution: Check for blob_alloc() returning NULL.

Replacement for Vim's test_null_string().
Vim uses it to verify that its codebase handles null strings.
Preparation for the Test_null_list() in patch v8.2.1822.
Use v:_null_string, not non-existent env var, for null string tests.
Mention v:_null_string in id() because id(v:_null_string) returns (nil).
1. When calling writefile(list, fname, []) do not show error message twice.
2. Do not allow file name to be overwritten for writefile([1], 2).
3. Do not show “Can’t open file with an empty name” error after error like
“using Float as a String” when type of the second argument is not correct.
4. Do not give multiple error messages and still continue for code like
`writefile(["test", [], [], [], "tset"])`.
Note that to fix 4. ideally I need tv_check_str_or_nr which is currently present
in two PRs: #6114 and #5119. I would want to avoid copying this function into
a yet another PR.
Ref vim/vim#1476.
