Summary:
By using low-level APIs, `environ` could contain ill-formed entries that do
not have the `NAME=VAL` form:
#define _GNU_SOURCE
#include <unistd.h>
char *envp[] = { "X", 0 };
char *argv[] = { "hg", "log", 0 };
int main() {
return execvpe("chg", argv, envp);
}
Ignore them silently so they won't break chg.

Summary:
Using windows libs like `_kernel32 = ctypes.windll.kernel32` means that
the `GetLastError` calls are useless.
(1317 is a non-existent process)
```
In [44]: k32 = ctypes.WinDLL('kernel32', use_last_error=True)
In [52]: ctypes.windll.kernel32.OpenProcess(0x0001, False, 1317)
Out[52]: 0
In [53]: ctypes.windll.kernel32.GetLastError()
Out[53]: 0
In [54]: k32.OpenProcess(0x0001, False, 1317)
Out[54]: 0
In [55]: k32.GetLastError()
Out[55]: 5
```
This behavior can explain why we can't auto-delete the stale lock file. See the `testpid` code:
```
def testpid(pid):
'''return True if pid is still running or unable to
determine, False otherwise'''
h = _kernel32.OpenProcess(_PROCESS_QUERY_INFORMATION, False, pid)
if h:
try:
status = _DWORD()
if _kernel32.GetExitCodeProcess(h, ctypes.byref(status)):
return status.value == _STILL_ACTIVE
finally:
_kernel32.CloseHandle(h)
return _kernel32.GetLastError() != _ERROR_INVALID_PARAMETER
```
The non-existent `pid` causes `h` to be `0` and `_kernel.GetLastError()` to also be `0` (see above why). This means that we think that this process exists!
(Note: this ignores all push blocking failures!)

Summary:
Change `insert_advanced` to accept an enum that could be either a key, or an
(offset, len) that refers to the external key buffer.
Insertion becomes slower due to new flexibility overhead. For some reason,
"index lookup (no verify)" becomes faster (restores pre-D7440248 performance):
index insertion 6.434 ms
index flush 3.757 ms
index lookup (memory) 1.068 ms
index lookup (disk, no verify) 1.969 ms
index lookup (disk, verified) 7.805 ms
With 2M 20-byte keys, the non-external key version generates a 105MB index:
seconds operation
1.247 insert
0.622 flush
1.859 flush done
0.702 lookup (without checksum)
1.395 lookup (with checksum)
Using external keys,the index is 70MB, and time for each operation:
seconds operation
1.086 insert
0.702 flush
0.665 lookup (without checksums)
1.602 lookup (with checksums)
The external key will have more space wins for longer keys, ex. file path.
`Index` module was made public so `InsertKey` type is usable.

Summary:
Previously, I thought there is only one index that will use "commit hash" as
keys, that is the nodemap, and other indexes (like childmap) would just use
shorter integer keys (ex. revision number, or offsets). So the space overhead
of storing full keys only applies to one index and seems acceptable.
But that implies strict topo order for the source of truth data (ex. to use
integers as keys in childmap, you have to know how to translate parent
revisions from hashes to integers at the time writing the revision).
Thinking about it again, it seems the topo-order requirement would make a lot
of things less flexible. It's much easier to just use hashes as keys in the
index. Then it's worthwhile to address the space efficiency problem by
introducing an "external key buffer" concept. That's actually what `radixbuf`
does.
This is the start. It adds the type to the strcut. The feature is not completed
yet.

Instead of looking up the `__len__` attribute, use the built-in `len()` function, which will raise `TypeError` if the wrapped manifest in a hybrid doesn't have a `__len__` method. This ensures that we get a consistent exception.

Summary:
p4seqimport has used very high level mercurial abstractions so far (almost
equivalent to running hg add / mv / rm / commit on command line). This is very
easy to grasp as we use it day to day. It is not performant enough for our
importer:
- It does the work twice (write to working copy, then commit changing hg metadata)
- It requires the working copy (this would force us to update between revs,
materializing a prohibitively large number of files)
This change makes use of memctx, which is basically an in-memory commit. This way
we don't need a working copy and we save time + a lot of space.
