* llama: wire up builtin runner
This adds a new entrypoint into the ollama CLI to run the cgo built runner.
On Mac arm64, this will have GPU support, but on all other platforms it will
be the lowest common denominator CPU build. After we fully transition
to the new Go runners more tech-debt can be removed and we can stop building
the "default" runner via make and rely on the builtin always.
* build: Make target improvements
Add a few new targets and help for building locally.
This also adjusts the runner lookup to favor local builds, then
runners relative to the executable, and finally payloads.
* Support customized CPU flags for runners
This implements a simplified custom CPU flags pattern for the runners.
When built without overrides, the runner name contains the vector flag
we check for (AVX) to ensure we don't try to run on unsupported systems
and crash. If the user builds a customized set, we omit the naming
scheme and don't check for compatibility. This avoids checking
requirements at runtime, so that logic has been removed as well. This
can be used to build GPU runners with no vector flags, or CPU/GPU
runners with additional flags (e.g. AVX512) enabled.
* Use relative paths
If the user checks out the repo in a path that contains spaces, make gets
really confused so use relative paths for everything in-repo to avoid breakage.
* Remove payloads from main binary
* install: clean up prior libraries
This removes support for v0.3.6 and older versions (before the tar bundle)
and ensures we clean up prior libraries before extracting the bundle(s).
Without this change, runners and dependent libraries could leak when we
update and lead to subtle runtime errors.
New lines can be an important part of a user's prompt and trimming
it can alter the results. We previously only trimmed prompts with
images but refactoring brought this behavior to all prompts, where
it became more noticable.
The /generate endpoint adds less whitespace and therefore doesn't
need to trim it out - this brings the same behavior to /chat.
Thanks to @gabe-l-hart for spotting the issue!

When processing a prompt, we look for image tags of the form
[img-0], which are inserted by the Ollama server process.
However, this can cause errors if the original prompt has these
tags - typically an image not found error is returned.
This changes tag searching behavior to be similar to the 0.3.x
series, which will largely avoid these problems. However,they can
still happen when input text with these tags is used with image
models. The correct solution is to escape the tags but this is a
larger issue with special sequences in general so this is an
incremental fix that should avoid the problem for the majority
of cases.
This also makes it easier to truncate long inputs the same as
shifting but does not actually implement it. This type of
truncation has a trade off between quality and time to first
token.
This changes makeRequest to update the http client Transport if and only
if testMakeRequestDialContext is set. This is to avoid overriding the
default Transport when testMakeRequestDialContext is nil, which broke
existing behavior, included proxies, timeouts, and other behaviors.

After a user pushes their model it is not clear what to do next. Add a link
to the output of `ollama push` that tells the user where their model can now
be found.
If there are no avilable slots for new sequences then a request
will not be added to the processing queue but will continue on
to wait for a response that never comes. Besides never giving a
response to the request, this prevents the model from being
unloaded due to the outstanding request.
To prevent this, there are semaphores that prevent more requests
from being processed than there are slots - one in the Ollama
server and one in the runner.
- The Ollama server one works but it is not designed to protect
the runner's data internal structures and the runner can return a
final response before clearing its data structures.
- The internal runner semaphore has similar behavior where it
can release the semaphore when it issues a response. This is
wrong - it should only release the semaphore after it has
cleared the data structure.
In addition, we should return an error if a slot is not found
rather than deadlocking in the event we ever get to this spot.
Fixes#7779
In the past the ollama.com server would return a JWT that contained
information about the user being authenticated. This was used to return
different error messages to the user. This is no longer possible since the
token used to authenticate does not contain information about the user
anymore. Removing this code that no longer works.
Follow up changes will improve the error messages returned here, but good to
clean up first.
Users get confused by "Failed to acquire semaphore" error="context canceled"
messages in the logs, which are actually clients giving up. While there could be
a legitimate hang bug in the system, sometimes this is just short client timeouts
with an overloaded system, so this should help users understand what's going on
better.
This avoids emitting the progress indicators to stderr, and the interactive
prompts to the output file or pipe. Running "ollama run model > out.txt"
now exits immediately, and "echo hello | ollama run model > out.txt"
produces zero stderr output and a typical response in out.txt
